Question

114 students choose to attend one of three after school activities: football, tennis or running. There are 53 boys. 53 students choose football, of which 27 are girls. 23 students choose tennis. 28 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

1/3

Explanation:

The attachment shows a table with the given information filled in. Since we know 53 chose football and 23 chose tennis, the remaining 38 must have chosen running.

Then 38 out of 114 students chose running. The probability that one of those is picked at random is ...

p(running) = 38/114 = 1/3
