Question

A die is rolled. What is the probability of rolling the following? A multiple of 3 or a multiple of 4

Answer 1

1) 33.33%

2) 16.66%

Explanation:

1) Since multiples of 3 in 1,2,3,4,5,6 include and limited to 3 and 6. This means that 2 / 6 or 1 / 3. This fraction is equal to 33.33%.

2) Since multiples of 4 in 1,2,3,4,5,6 include and limited to only 4. This means that 1/6 and this fraction is equal to 16.66%.

Answer 2

1/2.

Explanation:

A multiple of 3 is 3 or 6 and a multiple of 4 is 4.

Probability(3 or 6) = 2/6 = 1/3.

Probability(4 ) = 1/6.

So Probability ( multiple of 3 or a multiple of 4) = 1/6 + 1/3

= 1/2.
