And how many of them satisfy these conditions, that it's an even number? Well, it could be a 2, it could be a 4, or it could be a 6. So the probability is the events that match what you need, your condition for right here. So three of the possible events are an even roll. And it's out of a total of six possible events. So there is a 3 over 6, the same thing as 1 half probability of rolling even on each roll. Now, they want to roll even three times.
