Answer :


Two die having 6 faces each when tossed simultaneously will have a total outcome of 62=36


Let P(A) be the probability of getting a sum equal to 5.


Let P(B) be the probability of getting 2 different numbers.


Probability of getting 2 different numbers


= 1 – probability of getting same numbers


= 1 – 1/6


=5/6



Let be the probability of getting a sum = 5 and two different numbers at the same time.


The sample space of



Tip – By conditional probability, where is the probability of occurrence of the event A given that B has already occurred.


The probability that the sum = 5 given that two different numbers were thrown:
