Jack's toy box contains 13 toy soldiers, 7 model airplanes and 5 dolls. What is the probability that a randomly chosen toy from the box will be either a model airplane or a doll?
Choose the correct choice from the following choices.
A) 35/252  B) 12/25  C) (7/25)+(5/24)  D) 20/25  E) 12
Probability of selecting either a model airplanes or a doll = 1 - ( Probability of Selecting a Toy )   Probability of selecting either a model airplanes or a doll = 1 - 13C1/ 25C1   Probability of selecting either a model airplanes or a doll = 1 - 13/25   Probability of selecting either a model airplanes or a doll = 12/25   Hence answer will be (12/25)
