The probability that a high school student in in the marching band is 0.47

so, P(M)=0.47

The probability that a student plays a varsity sport is 0.32

so, P(V)=0.32

the probability that a student is in the marching band and plays a varsity sport is 0.24

so, we get

P(M∩V)=0.24

a student plays a varsity sport if we know she is in the marching band

so,

P(V|M)=(P(V∩M))/(P(M))

now, we can plug values

and we get

P(V|M)=\frac{0.24}{0.47}

P(V|M)=0.51063

So,

the probability that a student plays a varsity sport if we know she is in the marching band is 0.51063......Answer

Harman [31]

We just need to do come computation:

40-16+10 = 40+(-16+10) = 40+(-6) = 40-6=34

-20+18+30 = -2+30 = 28

So, we have 34>28
