A store has 80 modems in its inventory, 30 coming from source A and the remainder from source B. Of the modems from source A, 20% are defective. Of the modems from source B, 8% are defective. Calculate the probability that two out of a random sample of five modems from the store’s inventory are defective. (A) 0.010 (M) 0.078 (X) 0.102 (D) 0.105 (E) 0.125
