Your video helped me finish my last two problems! I was stuck on them for 35 minutes until I looked up a video and found this. Within 5 minutes I had both of them completed and they were right!! Thank you so much for your help!
I cant tell you how long i have struggled with understanding this. I have had numerous meetings with my professor. told her i am struggling. she explained ideas but never mentioned there was a formula. the study material is so hard to navigate that i cant find what i need to learn. i applied the formula you used and now i know what is going on! all this time wasted on struggling and you cleared it up in 8 minutes. thank you!
a MALE, given that SHE is right handed, L. THINK AGAIN KIDS. He says the person, he knew the mistake was there, but I think you should have fixed it. Anyway this helped LOoL. TY good man, ty.
The "she" refers to "the person", which is a feminine noun in French. (French is my first language.) If you find it confusing, replace "she" in this case by "the person". Cheers!
For question (a), "she" refers to the "person", which is a feminin noun in French. If you find this confusing, then simply replace "she" by "the person".

The set of all males and the set of all females are disjoint, or they have no common elements. Thus the probability of being male and female is the intersection of two disjoint sets, or the empty set, which is 0. This assumes someone doesn't identify as both genders...
+Tiffastic Nguyen Hi In reply to your comment, the number you have for P(R | M) is incorrect. This figure should be (0.41/0.49), as it represents the probability that the person chosen is right handed, given that they are male. Explaining it another way, if we pretended that the survey was of 100 people, and so multiplying the numbers in the table by 100 gives actual numbers of people instead of percentages - Then P(R | M) represents "what is the probability that a randomly selected person is right handed, given that they are male". There are 49 males, and 41 of them are right handed, so P(R | M) = 41/49. Going back to what the video states - that P(M n R) = 0.41 - this information comes from the table. P(M n R) means the probability that a person is male and right handed. Using my sample size of 100 scenario again, there are 41 people in this category, out of a total 100. I think the confusion has come from the similar notations used in probability, namely - P(R | M) vs P(R n M), where: P(R | M) = prob. of R (GIVEN) M, and P(R n M) = prob. of R (AND) M. At the risk of repeating myself, with conditional probabilities, like P(R | M), the sample size changes. It changes to be the sample size of the condition being applied, in this case M (Male). With probability of intersecting events, like P(M n R), the sample size is the entire population. As a final comment, with your statement regarding a tree diagram, I think that your calculated number "0.49*0.41" represents the intersection of (M) with (M n R), or rewriting your whole statement correctly, it would read: P(M n (M n R)) = P(M) * P(M n R) = 0.49 * 0.41 As a Venn diagram, this would be represented by a larger circle (M) fully containing a smaller circle (M n R), where (M n R) = 0.41, and M = 0.49, with 0.08 outside the smaller circle, which is of course the males who are left handed.
nice explanation, but the gender mixup is utterly confusing.
Geoffrey Woodland Substituting "she" by "the person" should clear up any confusion.
Thanks!
LOL. i love it when they work out the problems by hand. they do not skip a lot of steps. they show their work

When you think of a probability as the ratio of the "size" of an event versus the "size" of the sample space, everything becomes much simpler. :-)
This rlly helped me a lot! I clearly understand this better than the examples given in my modules. Thanks : )
Excellent! Thank you, Sir. You are better than my math teacher.
WAIT I GOT IT NOW! except for the sex mix ups, this is spot on easy and explained very well. good show mate.
Please try to listen, he said "The person" instead of She, He knows about the mistake
Please try to listen to him instead of reading

Omg you freakin saved meeee. I’m taking a test tmr and sis is stress and pressed👏🏾💕thank youuuuuu
Soooooo HELPFUL 👍👍🔥🥳 THANK YOU.... Finally understood how to solve union and intersection problem 😃
God I swear this helped me understand the concept better thanks so much.
i am revising for a entry exam u helped a lot
Thank you for this lesson. I am grateful
This has helped so much in categorizing them easily for the formula. Thx for the video.
Me reading: A male given that "she" is right handed.
Me: 😧
BTW this helped. Thank's and more power to your channel. 😊
The "she" refers to "the person", which is a feminine noun in French. (French is my first language.) If you find it confusing, replace "she" in this case by "the person". Cheers!
Hahahah I was also perplexed but then got it..😂
brilliant explanation, finally got my head around this chapter
what is "she is male" ? i dont understand this statement grammatically
Read the description under the video. ;-)
@@slcmathpc woaahh bro is replying to comments even after fkin 10 years??
Thank you so much it took so long to find the right explanation of it that used tables
Thanks a lot. It is so helpful. Now it makes way more sense to me
What if conditional probability of a pdf?
Amazing. This is really helpful for me.thanks a lot
:-)
Thank you so much! better explanation than my teacher
hahahaaha
/
That little "oops" 😂😊
Anyways ,thank you it was a really helpful explanation.
Nice explanation thank you sir.
LOL when He saw it he took like a small pause and realized WTF. And just went with it. LoL
When life gives you lemon... :-)
I am so confused. Shouldn't it be "given that he is right-handed," instead?
For question (a), "she" refers to the "person", which is a feminin noun in French. If you find this confusing, then simply replace "she" by "the person".
Dont assume his gender
Oh my god. Is this what you come here for?
Alright I’ll call she or him it then
This video was very helpful.
It was very helpful
Thank you
great work........@PC
شكرا لك اخي الحبيب
My rational thinking against my imagination. This make me really confuse
Woooow "A male given that she is right-handed" thank you math you never fail to confuse the fuck out of me
The "she" refers to "the person", which is a feminine noun in French. (French is my first language.) If you find it confusing, replace "she" in this case by "the person". Cheers!
@@slcmathpc I love you man but they shouldn't add that lgbt+ bullshit in my math questions it will confuse idiots like me
Hello sir. Can i ask a question?? Are you a math teacher sir??
+dhex acol You can always ask.
guys the gender issue isn't his problem he simply got the printout, so technically its the person who wrote the printouts problem
Replacing "she" by "the person" should clear things up. :-)
Can you please tell me the probability of MALE and Female.
The set of all males and the set of all females are disjoint, or they have no common elements. Thus the probability of being male and female is the intersection of two disjoint sets, or the empty set, which is 0. This assumes someone doesn't identify as both genders...
Thanks sir now I understand it🙂
Nice and simple!
P(M n R) = P(M) * P(R | M) = 0.49 * 0.41 A tree diagram would justify this. I think your calculation that P(M n R) = 0.41 is incorrect.

I agree
@@tomrose4560i agree
i was like WTF ?!? when i saw she is a male then i realized that he said we should correct it with "person" lol
but after a 10 years , thanks a lot ! you made me understand this topic which other 5 videos failed to do :D
Thank you so much!
Thanks sir
Thank you!
Sir 0.41÷0.86=0.476
Thank you.
Awesome!
male is he, and female is she. Thanks!
Thanks indeed. It's so clear and understandable.
thank you ..sir
Thanks
Tank You.
"she is a male " ? in b)
She is a Female not Male............
This helped so much goddam
Great awesome explanation
Awesome
Great
Thanks she
She is male
He female 😮
Honestly. All problems with genders assume gender pronouns. Where's our male she's and female he's? lol.
this video was gonna make me question the things i know about this topic, I don't recommend this video
💜💚💙💙💜💚
lol, I thought (a) and (b) would be 0 because of the weird gender pronouns
Simply read the comment in the description; it should clear any confusion.
Thks
Thank you!
THANK YOU
thanks
