A group of patients who are trying to lose weight report who exercises and who diets. The information is presented in the following Venn diagram.

A Venn diagram with a universal set contains two intersecting circles labeled Exercise and Diet that divide the set into four regions labeled as follows, where the region is given first and the content is given second: Exercise only, 25; Exercise and Diet only, 30; Diet only, 15; Outside the circles only, 5.

If a patient is selected at random from the group, what is the probability that the patient exercises or diets (or both)?
