Question

A dice is thrown once the proability of getting the square of the number appearing an the dice to be a multiple of 9

Answer 1

Find the total possible outcome:

A dice has 6 sides

Therefore the total possible outcome = 6

Find the squares of the numbers on each side:

1² = 1

2² = 4

3² = 9 {Which is a multiple of 9)

4² = 16

5² = 25

6² = 66 (Which is a multiple of 9)

Find the total favourable outcome:

Total number of favourable outcome = 2

(Which is 3 and 6)

Find the probability of getting the square of the number appearing an the dice to be a multiple of 9:

P(square is a multiple of 9) = 2/6 = 1/3

Answer: The probability is 1/3
