A man is know to speak truth 3 out of 4 times. He throws a die and reports that it is 6 . Then the probability that it is actually 6 is

Options

  1. A3 4
  2. B1 4
  3. C3 8
  4. D5 6

Correct answer

C. 3 8

Step-by-step solution

Probability of man speaking truth = 3 4 Probability of telling lies = 1 4 Probability of a die actually showing 6= ( 1 6 3 4 ) ( 1 6 3 4 )+ ( 5 6 1 4 ) = 3 8
