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

SOLUTION

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

$\frac{3}{6}$

Also there is only 1 face with 1.

So probability of getting a 1 is

$\frac{1}{6}$

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

$\begin{gathered} \frac{3}{6}+\frac{1}{6} \\ \frac{3+1}{6} \\ =\frac{4}{6} \\ =\frac{2}{3} \end{gathered}$

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