The Gallup poll asked respondents if they had taken a vacation in the last year. The respondents were separated into two groups: those who had graduated from college and those who had not. Numbers in the table are based on sample sizes of 250 in each group.

a. If a person is randomly selected from this group, find the probability for the following:

i. The person is a college graduate

ii. The person took a vacation

iii. The person is a college graduate and took a vacation

b. Which group is more likely to have taken a vacation in the last year: college graduates or non–college graduates? Support your answer with appropriate statistics.
