Asked by Mark

A committee of 2 is to be chosen at random from a group of 6 students consisting of 3 boys and 3 girls. What is the probability that a committee of 2 girls will be chosen?
Answered by Tammy
If you can't figure out the the weird format the bot is using .....

number of ways for your selection ---- no boys, 2 girls
= C(6,0)*C(3,2) = 3

number of ways to choose any 2 = C(9,2) = 36

prob(2 girls ) = 3/26 = 1/12

btw, looks like the bot is wrong again

Sorry, I misread the question, there are only 6 students in total,
I read it as 9, the 2nd last line should say:

prob(2 girls ) = 3/C(6,2) = 3/15 = 1/5

Miracles still happen apparently, the bot was right, and I was wrong!!
