Question

In a class of students, the following data table summarizes how many students play an instrument or squirt. What is the probability that a student who plays this for also plays an instrument?

​

Answer 1

Explanation:

What's a squirt? Did you mean sport for the word for?

So there are 15 separate students in all who play a sport and an instrument. There are 4 more that play an instrument, but not a sport.

There are 8 that that do not play an instrument including 2 that don't do either.

So the total is 15 + 4 + 8 = 27

My best guess is that 15 out of 27

P(sport and instrument) = 15 /27 = 5/9 or 0.556
