**(C) 0.75**

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.**
