Question

a total of 50 people attended a conference and were offered a choice of 4 types of entrees. the table shows the number of people who chose each type of entree.
if one of these people is selected at random, what is the probability of selecting a person who chose a vegetarian entree? (express your answer as a decimal or fraction, not as a percent.)

Explanation:

Step1: Use the probability formula

The probability formula is \(P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). Here, the number of favorable outcomes (people who chose vegetarian entree) is \(9\), and the total number of outcomes (total people) is \(50\). So the probability is \(\frac{9}{50}\).

Step2: Simplify the fraction (if needed)

\(\frac{9}{50}=9\div50 = 0.18\)

Answer:

\(0.18\) or \(\frac{9}{50}\)
