We want P(does not play an instrument | plays a sport) = P(does not play an instrument and plays a sport) / P(plays a sport).

From the table, among those who play a sport there are 5 who play an instrument and 14 who do not, so total 19. The number who do not play an instrument and play a sport is 14.

Thus the probability = 14/19 ≈ 0.7368 (about 73.7%).
