Question

Two dices are thrown at same time and the product of number appearing on them is noted find the probability that the product is a prime number

Answer 1

Probability = total no of favourable outcomes/total no of all possible outcome

2dice - 1,1,2,2,3,3,4,4,5,5,6,6

prime no -2,2,4,4,6,6

total no of favourable outcomes=6

total no of all possible outcome-12

probability=6/12=1/2

Answer 2

Answer:

1:1, 1:2, 1:3, 1:4, 1:5, 1:6

2:1, 2:2, 2:3, 2:4, 2:5, 2:6

3:1, 3:2, 3:3, 3:4, 3:5, 3:6

4:1, 4:2, 4:3, 4:4, 4:5, 4:6

5:1, 5:2, 5:3, 5:4, 5:5, 5:6

6:1, 6:2, 6:3, 6:4, 6:5, 6:6.

this is the probability and if you add this you will get a prime number.
