Answer:
The probability that a male chosen at random watches drama is 0.1333.
Step-by-step explanation:
The complete question is:
A survey asked 30 people what their favorite genre of television broadcasting was, and the results were tabulated above. Find the probability that a male chosen at random watches drama.
Male Female Total
Sports 8 3 11
Drama 2 6 8
Comedy 5 6 11
Total 15 15 30
Solution:
The conditional probability of an event <em>A</em> give that another event <em>B</em> has already occurred is:

Denote the events as follows:
<em>M</em> = a male was selected
<em>D</em> = a person's favorite genre is drama
The number of males in the survey is, <em>n</em> (M) = 15.
The number of males in the survey who watches drama is, <em>n</em> (M ∩ D) = 2.
Compute the probability that a male chosen at random watches drama as follows:

Thus, the probability that a male chosen at random watches drama is 0.1333.
