Number of children in the survey = 364
Number of children who liked to eat potato chips = 91
∴ Number of children who did not liked to eat potato chips
= Number of children in the survey − Number of children who liked to eat potato chips
= 364 − 91
= 273
Now,
P(A child selected at random does not like to eat potato chips)
=
=
=
Thus, the probability that a child selected at random does not like to eat potato chips is .
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 eat potato chips, is .
