A certain store sells small, medium, and large toy trucks in each of the colors red, blue, green, and yellow. The store has an equal number of trucks of each possible color-size combination. If Paul wants a medium, red truck and his mother will randomly select one the trucks in the store, what is the probability that the truck she selects will have at least one of the two features Paul wants? Choices
A) 1/4
B) 1/3
C) 1/2
D) 7/12
E) 2/3
No. of colors=4   no. of sizes=3   Total outcomes=12   Remaining outcomes=6   hence probability that truck is neither red nor of medium size is 6/126/12.   hence probability that the truck she selects will have at least one of the two features Paul wants will be 1−6/121−6/12 or 1/2   ANSWER:1/2
