To average 20 points in 4 games he needs a total of 20 x 4 = 80 points.
So far he has 13 + 21 + 32 = 66 points.
He will need 80 - 66 = 14 points in the 4th game.

Answer:
![\dfrac{1}{10}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B10%7D)
Step-by-step explanation:
Probability of the captain hitting the pirate ship ![=\dfrac{1}{2}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D)
Probability of the pirate hitting the captain's ship ![=\dfrac{1}{5}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B5%7D)
If both fire cannons at the same time, the probability that both the pirate and the captain hit each other's ship
=P(Captain Hits AND Pirate Hits)
=P(Captain Hits) X P(Pirate Hits)
![=\dfrac{1}{2} X \dfrac{1}{5}\\\\=\dfrac{1}{10}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D%20X%20%5Cdfrac%7B1%7D%7B5%7D%5C%5C%5C%5C%3D%5Cdfrac%7B1%7D%7B10%7D)
