Based on his past record, luke, an archer for a college archery team, has a probability of 0. 90 of hitting the inner ring of the target with a shot of the arrow. Assume that in one practice luke will attempt 5 shots of the arrow and that each shot is independent from the others. Let the random variable x represent the number of times he hits the inner ring of the target in 5 attempts. The probability distribution of x is given in the table.
