Based on the data you have P(Selena gets a hit)=8/20
and P(Tracey gets a hit) = 6/16
Since their hitting is independent (meaning that Tracey
does or doesn't get a hit simply because Selena does or
doesn't get a hit) you should multiply their respective
probabilities to get the probability they will both get
a hit at their next time at bat.
