Answer : C

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 likes to eat potato chips is 

=\frac{91}{364}

If a child is selected at random, the probability that he/she does not like to eat potato chips is

=1-\frac{91}{364}

 =\frac{364-91}{361}=\frac{273}{361}=0.756

In the options given, the closest to 0.756 is 0.75

Therefore option (C) is correct.
