Question

4. When die is thrown , list the outcomes of a prime number:---​

Answer 1

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

Prime numbers are those numbers which has only 1 and itself as a factor.

Solution :-

In a single die there are 6 possible

outcomes :- 1, 2 , 3 ,4 ,5 and 6

In a single die there are 3 prime numbers (successful outcomes) = 2 , 3 , 5

Probability = favorable outcomes / total outcomes

Therefore,

The probability of getting a prime number when a single die is thrown :-

P(E) = 3 / 6

= 1 /2

So ,when die is thrown there are the 1/2 (50%)chances that we get prime numbers
