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) $\frac{1}{4}$

(b) $\frac{1}{2}$

(c) $\frac{3}{4}$

(d) $\frac{4}{5}$

Answer 1

ANSWER:
Total number of children surveyed = 364
Number of children who liked to eat potato chips = 91
Number of children who do not liked to eat potato chips = 364 − 91 = 273
∴ P(Child does not like to eat potato chips)
= Number of children who do not liked to eat potato chips/Total number of children surveyed=$\frac{273}{364}$=$\frac{3}{4}$
Hence, the correct answer is option (c).
