If you roll a standard six-sided die, what is the probability that you get a 1 or 5? Give your answer as a simplified fraction.

Answer: 1/3

There are 6 sides. Both of those numbers are two numbers, so it would be 2/6. To simplify it, divide the top and the bottom by the same number. I divided both the numerator and the denominator by 2.

then, your answer would be 1/3

Step 1: Theorem


\text{Probability of an event = }\frac{N\text{umber of required outcome}}{N\text{umber of sample space}}

Step 2: Given data

Sample space = { 1, 2, 3, 4, 5, 6}

Number of sample space = 6

Event space = {1, 5}

Number of event space = 2

Step 3: Substitute to find the probability that you get 1 or 5


\begin{gathered} \text{Probability that you get 1 or 5 = }(2)/(6) \\ =\text{ }(1)/(3) \end{gathered}
