Concentric circles of radius 1 and 3 inches are drawn on a circular target of radius 5 inches. A man receives 10, 5 or 3 points according if he hits the target, inside the smaller circle, inside the middle annular region or inside the outer annular region respectively. Suppose the man hits the target with probability 4 and then is just as likely to hit one point of the target, as the other. Find the expected number E of points he scores each time he fires.

Question

Concentric circles of radius 1 and 3 inches are drawn on a circular target of radius 5 inches. A man receives 10, 5 or 3 points according if he hits the target, inside the smaller circle, inside the middle annular region or inside the outer annular region respectively. Suppose the man hits the target with probability 4 and then is just as likely to hit one point of the target, as the other. Find the expected number E of points he scores each time he fires.

Problem#4: Concentric circles of radius 1 and 3 inches are drawn on a circular
target of radius 5 inches. A man receives 10, 5 or 3 points according if he hits
the target, inside the smaller circle, inside the middle annular region or inside
the outer annular region respectively. Suppose the man hits the target with
probability 4 and then is just as likely to hit one point of the target, as the
cther. Find the expected number E of points he scores each time he fires.
