Question

the graph shows the results of a survey that asked people to choose their favorite dinner foods. one of the persons surveyed is chosen at random. what is the probability that she chose beef? favorite dinner foods potatoes 6 vegetables 8 fish 10 beef 18 chicken 24 pasta 14

Explanation:

Step1: Calculate total number of people surveyed

$6 + 8+10 + 14+18+24=80$

Step2: Calculate probability of choosing beef

The number of people who chose beef is 18. Probability $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$, so $P=\frac{18}{80}=\frac{9}{40}$

Answer:

$\frac{9}{40}$
