Asingle standard number cube is tossed. what is the probability of getting a 4 or a 5

The probability of getting a 4 or a 5 =

Step-by-step explanation:

A single standard number cube is tossed.

The standard cube named 1, 2, 3, 4, 5, 6.

Therefore, the sample space = {1, 2, 3, 4, 5, 6}

That is, the total number of possible outcomes = 6

We have to find the probability of getting a 4 or a 5.

Therefore, the favorable outcomes are = {4, or 5} = 2

We know that the probability of an event = The number of favorable outcomes / The total number of possible outcomes.

Now plug in the numerical values in the above formula.

The probability of getting a 4 or a 5 =

We can simplify this probability.

Divide both the numerator and the denominator by 2, we get

The probability of getting a 4 or a 5 =
