Lovely video sir, was very confused on this topic when i learnt it at first at school, but now i have a better view and new approaches to deal with questions, thank you
8:11 here the answer. Should we divided by two factorial.. bcz let’s say . The two teams members are (A,B,C,D) & (E,F,G,H). This is considered as a team. Then again it could be like (E,F,G,H) & (A,B,C,D) . Even though.. so it’s quiet clear both are same . Teams. So div by 2 factorial
In 8:49 why we don't multiply the resulting number by 2 coz one case is for Team 1 to have all boys and Team 2 all girls and the other case can be for Team 1 to have all girls and team 2 all boys?
great video but i had a question. on 17:22 for part iv, why cant i do 3x3P3x3? 5 dashes, so the first one has 3 options, last one also has 3 options and since repetition is not allowed, only 1,3 and 5 is left so hence 3P3. id greaaattttlllyyy appreciate an answer.Thank you!!
The reason why we can't is because this is a conflict situation meaning that the number you're keeping in the first place can also be in last place so it's best to break it up and do it one by one
5 ii) The security code starts with a letter and finishes with a symbol, why is it 6P4 if no letter can be repeated? Isn't it 4P4 because the two symbols are already used?

@@MathletebySaad yeah like 6 can be in first also last place and same with 8
5 ii) The security code starts with a letter and finishes with a symbol, why is it 6P4 if no letter can be repeated? Isn't it 4P4 because the two symbols are already used?

Sir love you yaar love you
Hello sir, love your videos!!! Would you be willing to to a live revision session for Addmaths before the exams plz?
Yeah I’ll do that inshAllah
In 17:04 why did you write 6,9. Didn’t you already write 6 at the beginning
Pls make video on 4024/N15/P21/Q.6
In b (ii) why do we multiply both the teams instead of adding them?
You beautiful man 😭😭😭🙏🙏🙏
