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

Sagot :

ANSWER

1/3

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,

[tex]P(3)=P(5)=\frac{1}{6}[/tex]

So,

[tex]P(3or5)=P(3)+P(5)=\frac{1}{6}+\frac{1}{6}=\frac{2}{6}=\frac{1}{3}[/tex]

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