Answer:
39/100
Step-by-step explanation:
The question asks to find the probability that a dormitory resident
chosen at random from this group has had a flu shot, given that he is male.
As for that, the first thing to do is to look at the column where it says male.
Male:
39-Had Flu Shot
12-Did not have Flu Shot
Since the question is asking for the total number of males who did get a flu shot, it would be 39.
Lastly, to find probability, you have to use part over whole. The part would be 39. The whole would be the number of people selected to be tested. Therefore, the whole would be 100. That is why the probability that a dormitory resident chosen at random from this group has had a flu shot, given that he is male would be 39/100.
