Question

For a certain class, the following data table compares how many students play an instrument or a sport. What is the probability that a student chosen randomly from the class plays a sport and an instrument?
Plays an instrument Does not play an instrument
Plays a sport 5 4
Does not play a sport 2 19

Answer 1

There are 5 students who play both. Total students = 5+4+2+19 = 30.

Probability = 5/30 = 1/6 ≈ 0.1667 (≈16.67%).
