Answer:

0.51

Explanation:

The probability that a high school student is in the matching band is,
P(M)=0.47

The probability that a student plays a varsity sport is,
P(V)=0.32 .

Th probability that a student is in the marching band and plays a varsity sports is ;
$P(M\cap V)=0.24$ .

The probability that a student plays a varsity sport if we know she is in the marching band is given by:

$P(V|M)=(P(M\cup V))/(P(M))$

P(V|M)=(0.24)/(0.47)

P(V|M)=0.51
