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

The relative frequency of size 6 shoe is given as

`(3)/(30)=(1)/(10)=10\%`

The probability of picking a shoe size of 7 is

`(6)/(30)=(1)/(5)`
