Question

A bag contains eight balls labeled 1 through 8. One ball will be randomly picked.What is the probability of picking an even number?Write your answer as a fraction.

Answer 1

`P(\text{even)}=(1)/(2)`

Step-by-step explanation

The bag contains balls labeled 1 through 8.

From 1 to 8, there are 4 even numbers and 4 odd numbers.

Therefore, the probability of picking an even number is the number of even numbers divided by the total number of balls.

That is:

`\begin{gathered} P(\text{even)}=(4)/(8) \\ P(\text{even)}=(1)/(2) \end{gathered}`

That is the answer.
