Question

The following frequency distribution shows the ages of India’s 63 richest individuals. One of these individuals is selected at random. Ages Frequency 30 up to 40 14 40 up to 50 3 50 up to 60 10 60 up to 70 20 70 up to 80 16 a. What is the probability that the individual is between 70 and 80 years of age

Answer 1

The probability that the individual is between 70 and 80 years of age is
`(16)/(63)`.

Explanation:

Given frequency table:

Ages Frequency

30 up to 40 14

40 up to 50 3

50 up to 60 10

60 up to 70 20

70 up to 80 16

Total 63

We need to find the probability that the individual is between 70 and 80 years of age.

`P=\frac{\text{Total number of individuals between 70 and 80 years of age}}{\text{Total number of individuals}}`

Total number of individuals between 70 and 80 years of age = 16

Total number of individuals = 63

`P=(16)/(63)`

Therefore the probability that the individual is between 70 and 80 years of age is
`(16)/(63)`.
