Question 22688: Selena and Tracey play on a softball team. Selena has 8 hits out of
20 times at bat, and Tracey has 6 hits out of 16 times at bat. Based on
their past performance, what is the probability that both girls will get a
hit next time at bat?

You can put this solution on YOUR website!
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.
Answer [(8/20)(6/16)]
