Question

A single six-sided die is rolled. What is the probability ofgetting an even number or a 1?Select one:1/2, 1/3, 1/6, 2/3

Answer 1

Now, on a die of 6 faces, we have 3 even numbers which are 2, 4 and 6

Probability is calculated as

`\frac{expected\text{ outcome}}{total\text{ outcome }}`

So, number of even number is 3, total die faces is 6

Probability of getting an even number becomes

`(3)/(6)`

Also there is only 1 face with 1.

So probability of getting a 1 is

`(1)/(6)`

Now, probability of getting an even number or a 1, means we add both, we have

`\begin{gathered} (3)/(6)+(1)/(6) \\ (3+1)/(6) \\ =(4)/(6) \\ =(2)/(3) \end{gathered}`

hence the answer is 2/3, the last option nswe
