Compute the probability.

Read the following and answer the questions.

Researchers are often interested in the likelihood of sampling outcomes. They may ask questions about the likelihood that a person with a particular characteristic will be selected to participate in a study. In this exercise, we will select a sample of one participant from the following hypothetical student population of men and women living on or off campus. The population is summarized in the following table.

	Male	Female	Row Totals
On campus	30	25	55
Off campus	20	25	45
Column Totals	50	50	100
