Helen plays basketball. For free throws, she makes the shot 78% of the time. Helen must now attempt two free throws. C = the event that Helen makes the first shot. P(C) = 0.78. D = the event Helen makes the second shot. P(D) = 0.78. The probability that Helen makes the second free throw given that she made the first is 0.86. What is the probability that Helen makes both free throws? |
Given that,
Consider C and D be the events Helen makes the first and the second shot respectively.
P (C) = 0.78
P (D) = 0.78 and
P (D|C) = 0.86.
The probability that Helen makes both free throws can be obtained as:
P (C AND D) =P (D|C) P (C)
= (0.86) (0.78)
= 0.6708
Therefore, the required probability is 0.6708.
