5C2 would be exactly two girls

You need to take that case, 3girls&2boys, 4girls&1boy, and 5girls&0boys.

All these cases should be considered.

[still dagger]

ques me at least 2 diya hai means you can have other cases where there are 3,4,5 girls if we take 5c2*9c3 we only take the case where there are only 2 girls and 3 boys

[ripe iris]

total - atmost two girls se nahi hojaaega?

[azure shadow]

yeah 5c2 are exactly 2 girls but then 9c3 se we can have cases of 2,3,4 or 5 girls

[azure shadow]

no...9c3 means selecting 3 from the 9 ppl left...and those 9 are like 3 girls and 6 boys...so we get all the cases i think

[azure shadow]

isliye toh doubt me pucha 💀

[still dagger]

when you take

9c3

you are not specifying

ki

tu kya leraha hai

[azure shadow]

but thats the point no? ki the 3 members in the committee can be girls or boys of any number

[still dagger]

dekh

when you're taking

9c3

you're combining the group of boys and girls

into a single group

without any distinguish

[azure shadow]

accha i think i get it...with 5c2 x 9c3 we would get those extra cases where humari committee me same members hai but ek case me 2 girls fixed aajaayegi from 5c2 and baaki cases me 9c3 se bhi voh aayengi...
