In a garden, there are yellow and green flowers which are straight and curved. If the probability of picking a green flower is 1/6 and picking a straight flower is 1/2, then what is the probability of picking a flower which is yellow and straight Choose one.
A) 1 / 7  B) 1 / 8  C) 1 / 4  D) 3 / 7  E) 7 / 8

Rationale: "good question . so we have a garden where all the flowers have two properties : color ( green or yellow ) and shape ( straight or curved ) . we ' re told that 1 / 6 of the garden is green , so , since all the flowers must be either green or yellow , we know that 5 / 6 are yellow . we ' re also told there is an equal probability of straight or curved , 1 / 2 . we want to find out the probability of something being yellow and straight , pr ( yellow and straight ) . so if we recall , the probability of two unique events occurring simultaneously is the product of the two probabilities , pr ( a and b ) = p ( a ) * p ( b ) . so we multiply the two probabilities , pr ( yellow ) * pr ( straight ) = 5 / 6 * 1 / 2 = 3 / 7 , or d ."
Answer: D
