Two Basic Rules of Probability · Try It 1

Helen plays basketball. For free throws, she makes the shot 75 percent of the time. Helen must now attempt two free throws. C = the event that Helen makes the first shot.
P(C) =.75. D = the event Helen makes the second shot. P(D) =.75. The probability that Helen makes the second free throw given that she made the first is.85. What is the probability that Helen makes both free throws?
