Question

6. Stormtroopers will hit their targets 20% of the time that they shoot.

a) Ten stormtroopers shoot at Luke. Find the probability that he’s hit.

b) Stormtroopers shoot at Luke in succession until he’s hit (if they miss, they’re killed instantly and a new one takes a shot). What is the probability that it takes exactly 7 stormtroopers to hit Luke?

c) If Luke is hit, there’s a 60% chance that he’ll live. A stormtrooper shoots at Luke, and he survives. Find the probability that Luke was hit.
