You roll a fair 6-sided dic.

What is P (roll an even number?

If necessary, round your answer to 2 decimal places.

Answer: 1/3

Step-by-step explanation: P (roll an even number) means the probability or the likelihood of rolling an even number.

Note that to roll an even number, we can roll a 2, 3, or 6 so there are three ways to roll an even number.

Now let's use our ratio for the probability of an event which is below.

Number of favorable outcomes/total number of outcomes

Since we want to find the probability of rolling an even number, the number of ways we can roll an even number will be in the numerator of our ratio.

Since there are three ways to roll and even number, we put 3 in the numerator of this ratio for our favorable outcomes. Also, remember that a number cube has six total outcomes. This means that a 6 will go on the bottom of our ratio sine a number cube has six sides.

So the probability of rolling an odd number

is 3/6 which can be reduced to 1/3.
