Q. 10

# Two dice were thr

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:
