She interviews 175 students and records their gender and a yes if they go at least twice a week and no if they go less than twice a week. She displays the results in the table. What is the probability that a person who does not go to the movies at least twice a week is female (round to the thousandth)?

Answer 1

D) 0.384

Explanation:

The question is looking for how many females do not go to the movies at least twice a week, so you need to look at how many females that said no.

28 females answered "no", out of a total of 73 people who answered "no," so you divide 28 by 73.

`(28)/(73) = .384`

Answer 2

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{(28)/(73)=0.384}`
