Suppose there are 15 jelly beans in a box (2 red, 3 blue, 4 white, and 6 green). A jelly bean is selected at random. What is the probability that the jelly bean is not red?
first you subtract the total number of red jelly beans from the total number of all jelly beans. 15-2=13 then you put how many you have left into a fraction over the total amount of jelly beans. 13/15 and divide them to get a percent. 13 divided by 15 equals 0.86666666667 so for a percent you move the decimal two to the right and you need to round 87%
