First, I assume in this question, supposedly you wanted to mention " 13 Female teaching assistant"

With that in mind, we have to find the total number of people in the mathematics department that is :

13+11+11+13= 48 total people

Now, find the probability (p) of a male professor which is:

Male professors: 13 People in total

Probability: Male professor/ total people

= 13/48

So, the probability of picking a male professor is: 13/48

Hope this helps.
