Six children are selected from a group of 10 boys and 12 girls. Find the probability that half are boys and half are girls. Thanks for your help!
-----
# of ways to select 3 boys: 10C3 = (10*9*8)/(1*2*3) = 120
# of ways to select 3 girls: 12C3 = (12*11*10)/(1*2*3) = 220
-------
# of ways to select 6 from 22: 22C6 = 74813
------------------------
P(3 boys and 3 girls) = (120*220)/74813 = 0.3538
