Question

4) What is the probability of getting a sum as 3 if a dice is thrown? 2/18 b. 1/18 c. 4 d.1/36​

Answer 1

Answer:

1/18

Explanation:

In two throws a dice, n (S) = 6 * 6 = 36

Let, E is the event of getting a sum of three.

E = (1, 2), (2, 1)

∴ n (E) = 2

∴ P (E) = n(E) / n(S)

           = 2 / 36

           = 1 / 18
