Question

In 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 milk as his or her primary drink.

Answer 1

Probability that the person preferred milk as his or her primary drink = 0.3

Explanation:

Given -

In a recent survey, 18 people preferred milk, 29 people preferred coffee, and 13 people preferred juice as their primary drink for breakfast .

Total no of people is = 18 + 29 + 13 = 60

If a person is selected at random ,

The probability of person preferred milk =
`(18)/(60)`

The probability of person preferred coffee =
`(29)/(60)`

The probability of person preferred juice =
`(13)/(60)`

Probability that the person preferred milk as his or her primary drink =

P ( milk ) =
`\mathbf{(No\;of\;favourable\;outcomes)/(total\;no\;of\:outcomes)}`

=
`(18)/(60)` = 0.3
