Question

How can I draw a frequency table to represent the information given? how can I calculate the realtive frequency of a size 6 shoe? How can I calculate the probability that if a pupil is chosen at random, that he/she wears a size 7 shoe?

Answer 1

SOLUTION

The relative frequency of size 6 shoe is given as

$\frac{3}{30}=\frac{1}{10}=10\%$

The probability of picking a shoe size of 7 is

$\frac{6}{30}=\frac{1}{5}$
