Probability of the pirate hitting the captain's ship

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)
![=(1)/(2) X (1)/(5)\\\\=(1)/(10)](https://img.qammunity.org/2021/formulas/mathematics/college/bxxfmyyvbmsp30k44entkky2qx90lu3d6r.png)
