Maria is in charge of the floating duck game at the pre-school fair this year. She put 11 floating ducks in a large pan. On the bottom of each duck is a picture of the prize you won.
3 ducks have a rubber ball picture
2 ducks have an apple picture
2 ducks have an airplane picture
3 ducks have a little stuffed dog picture
1 duck has a large teddy bear picture
What is the probability of winning either a teddy bear or an airplane in a single try?
