N a recent survey, 18 people preferred milk, 29 people preferred coffee, and 13 people preferred juice as their primary drink for breakfast. If a person is selected at random, find the probability that the person preferred juice as his or her primary drink.

Step-by-step explanation:

18 people preferred MILK

29 preferred COFFEE

13 preferred JUICE

We want probability that a person preferred JUICE. For that, we need number of people who preferred juice and total number of people.

Lets find total:

18 + 29 + 13 = 60 total people

Total people who preferred JUICE is:

13

Probability (preferred JUICE) = 13/60

The answer is  

1/2*qr*rs
