At a fundraiser, each person in attendanceis given a ball marked with a different number from1 through x. All the balls are then placed in an urn, and aball is chosen at random from the urn. The probability thata particular ball is selected is 1/x. So the probability that aparticular ball is not chosen is 1 - 1/x. Graph P(x) = 1 - 1/x using transformations. Comment on the probability aparticular ball is not chosen as x increases.
