Example text

And, maybe after some trial-and-error or scratch work, decide on 5. Write the 5 above the long division sign like this: 5 2 g10 Next take the 5 and multiply it times the divisor, 2, which yields 10, and write this below our dividend 10 like this: 5 2 g10 10 Finally subtract down, like this: 5 2 g10 - 10 0 The fact that you got a 0 at the end of this process means that 10 things can be divided evenly into 2 groups—there aren’t any leftovers. Most of the time in this chapter we’ll stick to division problems that come out evenly, although in the following example we’ll see what can happen.

If a standard die is tossed twice, what is the probability that the sum of the two numbers rolled will be an 11? A. 1 1 B. 2 C. 1 18 D. 12 E. qxd 5/20/03 9:14 AM Page 19 19 Pretest 93. If a card is drawn at random from a standard deck (excluding jokers), what is the probability that the card drawn is a king or queen? 1 A. 26 B. 10 1 C. 2 D. More than 10 E. None of the above 94.
