Question

11) A 12-sided dic is rolled. What is the probability of getting a multiple of 3 or a number less than 3?

Answer 1

6/12

1/2

Explanation:

First, we need to find how many multiples of three there are, and how many numbers less than three there are on a 12 sided die.

Multiples of 3: 3, 6, 9 ,12

Less than 3: 2, 1

When calculating the probability of rolling a number, the actual number is arbitrary- instead, you need to know how many of numbers exist to fit the requirements. In this case, it's 6 total. Since there's 12 possibilities on a 12 sided die, the probability would be 6 out of 12. You could also simplify the fraction, but both are equivalent.

I hope this helps!
