Question

A single die is rolled twice. Find the probability of rolling a 5 the first time and a 2 the second time.

Answer 1

The correct answer is 1/36

Explanation:

It is given that, single die is rolled twice

The sample space consists of,

(1, 1), (1, 2) ....... (1, 6)

.

.

(6, 1) ............. (6, 2)

Total = 36

To find probability

The possible outcome is (5, 2)

The probability of rolling a 5 the first time and a 2 the second time = 1/36

the correct answer is 1/36

Answer 2

= 1/36

Explanation:

The probability of roiling a 5 is 1/6, while,

that of rolling a 3 is 1/6

Therefore;

The probability of having a 5 the first time and a 3 the second time will be the product of the probability of having a 5 and the probability of having a 3.

= 1/6 × 1/6

= 1/36
