The table below shows the results of a survey of 250 people who were asked whether they like to read and whether they play a musical instrument.
According to the results, what is the probability that a randomly selected person who was surveyed likes to read, given that the person plays a musical instrument?
The correct answer is B.
According to the table, 90 people play an instrument but only 50 of those 90 people like to read.
Therefore, the desired probability is 50/90 = 5/9.
