ANSWER

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
