Question

In a survey of 120 grade 5 pupils, 50 do not like to watch Pinocchio. Find p and q where p was the proportion of children who like to watch the film.

Answer 1

Solution:

$n=120$

p was the proportion of children who like to watch the film.

And 50 do not like to watch Pinocchio.

So, (120-50=) 70 like to watch Pinocchio.

$p=\dfrac{70}{120}=\dfrac{7}{12} \\ q=\dfrac{50}{120}=\dfrac{5}{12}$
