Question

Two hunters aim at a target. The probability that the first will hit it is 1/5 while the probability that the second will hit it is 2/7. Find the probability ,
a. Both will hit the target
b. Only the first will hit it
C. One of them will hit it
D. Both of them will miss it

Answer 1

P(hit,hit) = 1/5 * 2/7
P(hit,miss) = 1/5 * 5/7
P(one hits) = 1 - P(both miss)
P(both miss) = 4/5 * 5/7
