Tim has 30 jellybeans, with equal numbers of three flavors-raspberry, pineapple, and orange. He likes raspberry the best. So far, Tim has eaten 6 orange and 4 pineapple jellybeans. What are the chances that the next one he picks will be raspberry?

Before Tim ate any of the jellybeans, here are numbers:

pineapple or p = 10

raspberry or r = 10

orange or o = 10

Tim has eaten 6 orange and 4 pineapple jellybeans. Hence, what's left are:

p = 10-4 = 6

o = 10-6 = 4

r = 10 so now total jelly beans are 20

So the probability of getting a raspberry is:

p (r) = number of r/total

10/20 or 50%
