What is the probability that there will be 2 defective items? In a box of 100 items23%of college students say they use credit cards because of the rewards program. You randomly select 10 college students and ask each to name the reason he or she uses credit cards. Find the probability that the number of college students who say they use credit cards because of the rewards program is (a) exactly two, (b) more than two, and (c) between two and five inclusive. If convenient, use technology to find the probabilities.

- You play a game of chance. You draw a card from a 52-card deck. You continue to draw until you have drawn a king (you win), or till you have drawn five cards (you lose if no kings among those 5 cards). Draw a trec diagram that illustrates the expcriment. Put the appropriate probabilities on the tree. Find the probability that you win before the fourth draw.A and B are independent events. Use the following probabilities to answer the question.
