Question

A six-sided number cube is rolled. Find the probability of rolling a 5 or an even number

Answer 1

You have the event, A={5,2,4,6}. Now you should use Laplace definition of probability.

Answer 2

What is the Laplace definition of probability?

Answer 3

\[P(A)=\frac{\text{Favorable cases}}{\text{All cases}}\]

Answer 4

In a six sided number you have 6 possible cases: {1,2,3,4,5,6}. Your favorable cases is the cases of set A={5,2,4,6}, so you have 4 favorable cases.

Answer 5

So it's 2/3?

Answer 6

Yes.
