Answer:
1/3
Step-by-step 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
