Question
A coin is tossed four times one by one. What is the
probability of getting a tail for the first time, head for the second time and again head for the third time, and a tail for the fourth time?Solution
Number of times the coin is tossed = 4
Probability of getting a tail for the first time = 1/2
Probability of getting a head for the second time = 1/2
Probability of getting a head for the third time = 1/2
Probability of getting a tail the fourth time = 1/2
=> Required probability = (1/2) (1/2) (1/2) (1/2) = 1/16
