A florist has 2 azaleas, 4 buttercups, and 5 petunias. The florist puts two flowers together at random in a bouquet. However, the customer calls and says that she does not want two of the same flower. What is the probability that the florist does not have to change the bouquet?
[ "43/55", "17/55", "8/11", "38/55" ]
D
The probability that two of the same flowers were chosen: P(AA) = 2/11 * 1/10 = 2/110 P(BB) = 4/11 * 3/10 = 12/110 P(PP) = 5/11 * 4/10 = 20/110 The sum of these probabilities is 17/55 P(two flowers are different) = 1 - 17/55 = 38/55 The answer is B.

If a store adds 20 chairs to its current inventory, the total number of chairs will be the same as three-halves the current inventory of chairs. If the manager wants to increase the current inventory by 50%, what will the new inventory of chairs be?
[ "160", "100", "140", "60" ]
D
Explanation: Let’s say t = total current inventory of chairs. The first sentence states that 20 + t = (3/2)t. First solve for the current inventory: 20 + t = (3/2)t 20 = (3/2)t − t 20 = (1/2)t 40 = t The manager wants to increase this by 50%. 50% of 40 is 20, so the new inventory will be 60. Answer: B
