Answer:
0.78125 or 78.125%
Step-by-step explanation:
Male professors = 7
Female professors = 6
Male T.A. = 12
Female T.A. = 7
Number of people in the department = 32
The probability that the selected person is a professor or a male is given by the probability that the person is a professor added to the probability that the person is a male, minus the probability that the person is a male professor:

The probability is 0.78125 or 78.125%
