A city council consists of seven Democrats and seven Republicans. If a committee of six people is selected, find the probability of selecting three Democrats and
three Republicans.
x people selected from n people by nCx ways ,
Where nCx = n! / [ (n-x)! * x! ]
So,
P(3 democrats and 3 Republicans) = 7C3 * 7C3 / 14C6
= 0.4079
