If A speaks the truth 80% of the times, B speaks the truth
60% of the times. What is the probability that they tell the
truth at the same time

Answer Posted / chinna

Probability of A, speaking the truth, P(A)=80 %
=80/100 = 4/5

Probability of B, speaking the truth, P(cool.gif=60 %
=60/100 = 3/5


the probability that they tell the truth at the same time is
= P(A) * P(cool.gif
= 4/5 * 3/5
= 12/25
= 0.48
