Start noticing that there are 6 + 7 = 13 persons, in total.

(a)  In   =  =  = 1287  ways.



(b)  In   =  = 20*35 = 700 ways.

Solved.

A note to the composer of the problem

            When you formulate the problem, do not use the word "distinct" when you say

                    "six distinct men and seven distinct women".

            It is clear even without your words that they all are distinct - they CAN NOT be identical.

Unnecessary words do not make your text stronger ---- in opposite, they make your text weaker.
