Assume the first two do
(7/16)(6/15)(9/14)(8/13)(7/12)(6/11).
But there are 6C2 ways the sample can be chosen. In all instances, the denominator will be the same, just ordered differently. Same with the numerator.
6C2=15
So it is the above product *15=
numerator is 127008
denominator is 5765760
The probability is 127008*15/5765760=
0.3304.
