Question

Find the probability of the event.If a single die is tossed once, find the probability of the following event. Rollinga 3 or a 5

Answer 1

1/3

Step-by-step explanation

If we have a fair die, the probability of rolling any of the numbers is the same. In this case, we want to know the probability of rolling a 3 or a 5, which is the sum of the probabilities of rolling each of these values,

`P(3)=P(5)=(1)/(6)`

So,

`P(3or5)=P(3)+P(5)=(1)/(6)+(1)/(6)=(2)/(6)=(1)/(3)`

Hence, the probability of rolling a 3 or a 5 is 1/3
