A health instructor surveyed all her students, and tallied the results. The first survey question asked, "Do you adhere to a vegetarian diet or omnivorous diet?" The second question asked, "Approximately how often do you exercise?"

Question

A vegetarian diet An omnivorous diet
Daily 2 1
Weekly 4 3
What is the probability that a randomly selected student exercises daily and adheres to an omnivorous diet?
Simplify any fractions.

Answer 1

First, find the total number of students surveyed:

2 + 1 + 4 + 3 = 10 students

Next, find the number of students who exercise daily and adhere to an omnivorous diet:

1 student exercises daily and adheres to an omnivorous diet

Therefore, the probability that a randomly selected student exercises daily and adheres to an omnivorous diet is:

1/10 = 0.1 or 10%
