Select the correct answer.
Musya8 [376]

Answer:

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%
