Question

A pair of dice is loaded. The probability that a 4 appears on the first die is 2/7, and the probability that a 3 appears on the second die is 2/7. Other outcomes for each die appear with probability 1/7. What is the probability of 7 appearing as the sum of the numbers when the two dice are rolled?

Answer 1

P1=1/7.1/7=1/49. similarly P2, P3, p5, P6 and p4=2/7.2/7=4/49
