Question

Do you go to the movies at least twice a week?

Answer 1

Answer:

We are given the below table of information:

                       Yes                No                  Total

Male                 35                  45                   80

Female             67                  28                   95

Total                  102                73                   175

We have to find the probability that a person who does not go to the movies at least twice a week is female.

We know that there are 73 students who does not go to the movies at least twice a week

Also we know that there are 28 female's who does not go to the movies at least twice a week.

Therefore, the probability that a person who does not go to the movies at least twice a week is female is:

$\bold{\frac{28}{73}=0.384}$
