Question

You roll a fair, six-sided number cube. How many times would you expect to roll an odd number if you roll the cube 200 times?

Answer 1

Answer:

100 times.

Explanation:

In a six-sided number cube:

• The total number of faces = 6

,

• The number of faces showing odd numbers, {1,3,5} =3

$\text{The probability of rolling an odd number}=\frac{3}{6}$

Therefore, if the cube is rolled 200 times:

$\begin{gathered} \text{The number of expected outcome }=\frac{3}{6}\times200 \\ =100 \end{gathered}$

You would expect to roll an odd number 100 times.
