Question

In a survey of 364 children aged 19-36 months, it was found that 91 liked to eat potato chips. If a child is
selected at random the probability that he/she does not like to eat potato chips is
(a) 0.25
(b) 0.5
(c) 0.75
(d) 0.80​

Answer 1

Answer:

Correct answer is 0.75

Explanation:

(c) Total number of survey children’s age from 19-36 months, n(S) = 364 In those of them 91 out of them liked to eat potato chips.

∴ Number of children who do not like to eat potato chips, n(E) = 364 – 91 = 273

∴ Probability that he/she does not like to eat potato chips = n(E)/n(S) = 273/364 = 0.75

Hence, the probability that he/she does not like to eat potato chips is 0.75
