P(s) = n(s)/N; where s is a successful outcome, n(s) is the number of possible successful outcomes, and N is the number of all possible outcomes from a single trial/experiment.
In your case n(s = mkt) = 100; N = 200 for the first question.
n(s = mgt|female) = 30; N(female) = 120 for the second
n(s = mgt|male) = 40: N(male) = 80 for the third
n(s = male) = 80; N = 200 for the fourth
You can do the math.
