The probability of rolling an even number first and an odd number second is 1/4.
<h3>What is the probability?</h3>
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability of rolling an even number first and an odd number second = (numbers that have the even number first and odd number second / total sample space)
9/36 = 1/4
