Abag contains 17 balls numbered 1 through 17. what is the probability of selecting a ball that has an even number when one ball is drawn from the bag?

To find the probability of drawing an even number, you will determine how many possible outcomes are even and divide by the total possible outcomes.

(2, 4, 6, 8, 10, 12, 14 ,16) = 8 possible even numbers
(1 - 17)                            = 17 possible outcomes

8/17 = 0.47

There is an approximate 47% chance of drawing an even number.
