A man is known to speak truth 3 out of 4 times. He throws a die & reports that it is a six. the probability that it actually six is.......?

• the probability that he speaks truth is 3/4
  and probability of a six is 1/6
  so probability that it is actually a six=1/6*3/4=1/8

  3/4 ( speak truth probability)*1/6(die probability)=

• 2/3
  because of probality of exactly 6 is 1/6 and speak truth is 4c3,so 4c3*1//6.
