Question

97 students choose to attend one of three after school activities: football, tennis or running. There are 45 boys. 36 students choose football, of which 11 are girls. 41 students choose tennis. 15 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

Answer:

20/97

Step-by-step explanation:

Since we are only looking at students in general that choose running, the question is more simple than it seems. We can ignore every phrase that is gender specific because it doesn't apply to our question. All we need to know is that there are:

97 students

36 who chose football

41 who chose tennis

And we just need to find the number that chose running

97-(36+41)=20

20 students chose running

20/97
