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

100 times.

Step-by-step 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}=(3)/(6)`

Therefore, if the cube is rolled 200 times:

`\begin{gathered} \text{The number of expected outcome }=(3)/(6)*200 \\ =100 \end{gathered}`

You would expect to roll an odd number 100 times.
