your question is ambigous, does it mean

one woman only or at least two women ?

If two women were selected, then " a woman was picked" is a true statement.

I will give both solutions:

what we don't want is all men

that would be C(6,2) = 15

prob all men = 15/45 = 1/3

so the prob of at least one woman is 1 - 1/3 = 2/3

if you want exactly one woman

number of ways = C(6,1) x C(4,1) = 24

prob of exactly one woman = 24/45 = 8/15
