Question

Of the 125 members of the marching band, 42 are in chorus, 78 play

Answer 1

Using it's concept, it is found that there is a 0.2979 = 29.79% probability that they are in chorus, given that they do not play a sport.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, 125 - 78 = 47 members of the band do not play a sport, of which 42 - 28 = 14 are in the chorus, hence the probability is given by:

p = 14/47 = 0.2979.
