There are 55 boys.
35 students choose football, of which 18 are girls.
30 students choose tennis.
14 girls choose running.
A student is selected at random.
What is the probability this student chose running?
Give your answer in its simplest form.

Answer 1

6/19

Explanation:

30 students out of 95 chose running.

30/95 can be simplified to 6/19 by dividing by the HCF of 5

Answer 2

Answer 34/95
Since 38 students choose football and 23 students chose tennis, then 95 - 38 - 23 = 34 students chose running. The probability is 34 / 95.
