probability of speaking truth is 0.75


and that of speaking false is 0.25


probability of coming 6=1/6

probabiliy that it is 6 and he say the truth = .75*1/6

probability that it is not 6 and he say it as 6 = .25*5/6

Probability that it is actually 6=(0.75*1/6) / {(0.75*1/6) + (0.25*5/6)}


                                             =3/8
