Mick has a bag with 2 mint sticks, 11 jelly treats, and 7 fruit tart chews. if he eats one piece every 10 minutes, what is the probability his first two pieces will be a jelly treat and a mint stick? give your answer in a percent.

First you add all the candies together to get 20 in the bag
2+11+7=20

jelly treat:
now we divide 11 by 20 to get a decimal
11/20= .55

multiply .55 by 100 to change it to a percentage
.55*100=55

first part of He has a 55% chance of getting a jelly treat 

mint stick:
divide 2 by 20 to get a decimal
2/20=.1

change .1 to a percent by multiplying by 100
.1*100=10

second part of he has a 10% chance of getting a mint stick
