The probability that all will be graduates will be 5/20 x 4/19 x 3/18. This equals 0.0087719, or 0.877% The probability of at least one being a graduate is 1 minus the probability of none being graduates. That's 1-(15/20 x 14/19 x 13/18)
= 1 - 0.39912280701754385964912280701754
= 0.600877
=60%
Thus the probability of having at least one graduate is 60%

What is the probability of having exactly 2 boys out of 6 children?
The answer depends on whether the children are picked at random. If they were selected from inside a girls' school the probability should be quite close to 0. Likewise, if the children were picked inside a boys' school. If six children are picked at random from a large group of children with an equal number of boys and girls, then the answer is 6C2*(1/2)6 = 15/32 = 0.47, approx.
