Question

Two dice are tossed the probability that the total score is a prime number is:​

Answer 1

Explanation:

The logic is there are six sides to each die, so for each number on one die you can pair with six different numbers on the other die. Therefore, the probability of rolling a prime number on two dice is 15/36, which reduces to 5/12 (E).

Answer 2

Answer:

1/2 or 50%

Explanation:

The total no. of prime no.s in a dice is three i.e., 2,3 and 5. We cannot consider 1 here because 1 is neither prime nor composite.

Then, if there is two dices then, the total no. of prime no.s will be 6.

Probablity of an event = Favourable outcomes/ Total no. of outcomes.

The total outcomes here are 12 because there are two dices.

Hence, the answer will be 6/12 or 1/2 or 50%.
