Question

The following frequency distribution shows the ages of America’s 30 richest individuals. One of these individuals is selected at random.

What is the probability that the individual is between 60 and 70 years of age? (Round your answer to 3 decimal places.)

What is the probability that the individual is younger than 50 years of age? (Round your answer to 3 decimal places.)

What is the probability that the individual is at least 60 years of age? (Round your answer to 3 decimal places.)

The following frequency distribution shows the ages of America’s 30 richest individuals. One of these individuals is selected at random.

a) between 60 and 70 years of age we have frequency = 10, relative frequency = 10/30 = (0.33)

which is the probability of getting a person in this age group

b) younger than 50, we have 2 groups with frequencies of 4+5 = 9, probability = 9/30 = (0.3)

c) at least 60. we have 10+5 = 15, probability = 15/30 = (0.5)
