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.)

type of entree	vegetarian	fish	chicken	beef
total	50

Explanation:

Step1: Recall probability formula

The probability $P$ of an event is given by $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$.

Step2: Identify favorable and total outcomes

The number of people who chose a vegetarian entree is 7 (favorable outcomes), and the total number of people is 50 (total outcomes).
So the probability $P = \frac{7}{50}$.

Step3: Convert to decimal (if needed)

$\frac{7}{50}=7\div50 = 0.14$

Answer:

$0.14$ or $\frac{7}{50}$
