There are 15 boys and 14 girls in a room. Two of
them are selected at random to take a survey. What is
the probability that the two people selected will be girls?
Dear ass. The probability from Answer is correct. The alternative
formula C(14,2)/C(29,2) gives the same result, where C(n,r) is the
number of combinations without repetition, n is the number of things
and we choose r of them
