Question

A man is known to speak the truth in 3 out of 5 times. He throws a die and reports that it is 4. Dind the probability that is actually that is a 4

Answer 1

Answer:

1/10

Step-by-step explanation:

To be actually 4 on dice

it is necessary that dice shows 4

and man speak truth

Now probability of Dice Showing 4 =  1/6

Now Probability of speaking the truth = 3/5

Probability of being actually 4 = (1/6) * (3/5)

= (1/2) * (1/5)

= 1/10

Hence 1/10 is the probability of actual being 4
