Question

Question 26
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) 0.50
C) 0.75
D) 0.80

Answer 1

The answer is C.
Total number of survey children’s age from 19-36 months, n(s) =364
91 out of them liked to eat potato chips.
$\therefore$ Number of children who do not like to eat potato chips, n(E) = 364 - 91 = 273
$\therefore$ Probability that he/she does not like to eat potato chips $=\frac{n\left(E\right)}{n\left(S\right)}=\frac{273}{364}=0.75$
