Question

The probability of getting a prime number on rolling a dice is

Answer 1

Answer:

Step-by-step 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

Step-by-step explanation:

Numbers on the dice(Total number of outcomes): 1, 2, 3, 4, 5, 6

Prime numbers: 2, 3, 5

No. of favourable outcomes: 3

$Probability=\frac{number of favorable outcomes}{total number of outcomes}$

= 3/6

=1/2

therefore, the probability of getting a prime number is 1/2.
