A twelve-sided die with sides labeled 1 through 12 will be rolled once. Each number is equally likely to be rolled. What is the
probability of rolling a number less than 4 ? Write your answer as a fraction in simplest form.
1 answer:
There are three numbers less than 4 that are on this die: 1, 2, and 3. These are the desired outcome, so this will be our numerator.
There are 12 total numbers on the die, so there are 12 possibilities of rolling the die. This will be the denominator.
This becomes 3/12, which can be simplified to 1/4.
Hope this helps!
