Answer:
0.611
Step-by-step explanation:
First, we need to get the total of people who answered the question in the poll.
In this case:
84(yes) + 73(no) = 157 people
With this we can know the probability of the people who only answered yes in the question, which is:
84/157
Now, we need to know the number of these people, who were male, regardless of his answer.
14 said yes and 12 said no, so: 14 + 12 = 26
the probability of this is: 26/157
Now from this group, only 14 said yes and were male so:
14/157
Finally to get the probability of choose a person that answered yes or was male is:
P = P(male) + P(yes) - P(male and said yes)
P = 84/157 + 26/157 - 14/157
P = 96/157 = 0.611464968 and rounded to the nearest thousandth it would be 0.611.
