A bowl contains candies of the same size in three flavors orange strawberry and pineapple. If the probability of randomly pullin
g out an orange candy is 1/9, and the probability of randomly pulling out a strawberry candy is 2/9, what is the probability of randomly pulling out a pineapple candy?
think about it this way, if you have only 3 different types of candy that you can pull from a bag, and the two candies probably is already listed, then you can find the third candy but taking the total about of the two listed probability of picking a candy (in this case it would be 3/9) and subtract that from the total amount of candies in the bag.
In the box containing the 2 plain pencils and 2 pens, there would be a 50% chance of getting a pen. In the other box containing 7 color pencils and 3 crayons there would be a 30% chance of getting a crayon.
