The probability that a high school student in in the marching band is 0.47. the probability that a student plays a varsity sport is 0.32. the probability that a student is in the marching band and plays a varsity sport is 0.24. what is the probability that a student plays a varsity sport if we know she is in the marching band? question 9 options: .51 .75 .32 .24

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

so,

The probability that a student plays a varsity sport is 0.32

so,

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

So,

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

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.
