I love how clear your voice is,plus thanks for breaking down this topic❤

[@WrathofMath]

Thank you for watching!

[@ea1766]

clear and concise video, good job bud

[@myintooookhin7439]

🎉 thanks a million!

[@shwetakulkarni3976]

Thank you so much for clear explanation 😊❤

[@WrathofMath]

My pleasure 😊

How does one determine that the ace is red. given that we have two options.

[@gerarddonovan4145]

Excellent explaination

[@WrathofMath]

Glad it was helpful!

how do we know there are two 4 and 2 red aces. Please can you explain properly

[@carolmcsween-brooks9519]

Since 1 is a prime number, shouldn't the set of numbers for a dice roll
that is prime be 1, 2, 3, and 5?

[@WrathofMath]

1 is not prime - a prime number is a positive integer with exactly 2 factors! But 1 only has one factor.

[@carolmcsween-brooks9519]

@@WrathofMath Thank you so much! Wow! In the 1950's and 60's I was taught that 1 was a prime number and if I'm not mistaken this was taught right through to my college calculus. Not sure why the teaching wasn't in agreement with the current mathematicians. Now that I'm working with data science this is a significant revelation - for me though it's sort of like being told that Pluto is no longer a "planet." :D From my perspective, I could still see how one could be considered prime - its second factor is itself. But the key is that the factors of a prime number have to be two DIFFERENT numbers. So, thanks again. Your explanation of the addition rule of probability is great. 🙂

Last question solution:
26/52 + 4/52 - 2/52 = 28/52
Is this Right?

[@WrathofMath]

Thanks for watching and great work, that's precisely right!

[@loll1165]

This might sound silly, but where do you get the 26 from like how do you know its 26 out of 52

[@Itachi_Zoldyck]

​@loll1165 you add the diamond and the heart since they are red so diamond got 13 out of 52 and heart got 13 out of 52😅 finally 13+13=26. (26/52)👍

[@teja4b132]

thank u sir
please make the video on total proability therom with example problems sir

[@WrathofMath]

Thanks for watching and here is my lesson on total probability: th-cam.com/video/U3_783xznQI/w-d-xo.html
I'll try to do a lesson with some more examples of applying it soon!

@@WrathofMath thank you sir

[@ahunaisrael9521]

Where did that two came from ...in the last question

[@astro_nic]

How to find again the (A intersect B)?

[@WrathofMath]

Thanks for watching! A intersect B is the set of all things common to both A and B. In terms of probability, A intersect B is "A and B". So if A = Rolling an even number and B = Rolling a prime number, then A intersect B is rolling an even and prime number, so the only outcome in that event would be rolling a 2.

HII THANK YOU FOR THE USEFUL TEACHING
PLEASE MAKE A VIDEO ON BAYES THEOREM

[@WrathofMath]

You're very welcome and thanks for watching! I'd be happy to make a video on Baye's Theorem, I'll try to do one soon! Thanks for the request!
