A professional pool player claims that she sinks at least one ball in a pocket on 80% of her opening break shots. In a recent se
t of 20 games, she sunk at least one ball on her break shot in only 14 of the games. A simulation of 100 trials was conducted to see how unusual these most recent games are.
Based on the dotplot of the simulation results and the pool player’s last 20 games, which conclusion can be drawn?
The player’s true probability of sinking at least one ball on her break is 27%.
Another 100 simulated trials would show a much different outcome; therefore, we cannot draw any conclusions.
It is most likely that she would sink at least one ball during her break exactly 16 times.
There is about a 27% chance of her sinking at least one ball on her break 14 or fewer times in 20 games. This result is not unusual and there is no convincing evidence that her average is less than 80%.

Please take the time to type in the question by yourself. I assume you use some kind of an apps to transcribe problems. It only confuses and discourages helpers. The fact that the question was reported means it is not clear.
I ASSUME the question is as follows:
Need to find P-G.
We see clearly that each expression P, G contains 3 terms, namely w^4, w^2z^2 and z^4. We will have to add/subtract like terms to get the answer.
(distribute negative sign into expression G)
(group like terms)
(add/subtract like terms)
