QUESTION 1: Chapter 1 of the text (1-13) you will look at calculating a monthly payment for a loan.  A simpler problem is to compute the amount a loan would cost you in one month. Using information from an internet source, determine the current interest rate a credit card or loan. Suppose you borrow $1,000 (or spend $1,000) on a credit card. How much will you owe in one month? 6 months if you pay nothing for 6 months? Compute the 6 month cost in two ways:  Make 6 monthly computations. Enter these as formulas in a spreadsheet. (The goal here is really getting you to use spreadsheets and formulas for computations.) Use the formula, A= 1000*(1 + r)^(N) where N = the number of periods (6) and r = the periodic interest rate = APR/12, where APR is the annual percentage rate.

The coin has two possible outcomes, heads or tails. a. List the sample space for the outcomes that could happen when tossing the coin four times. For example, if all four coin tosses produced heads, then the outcome would be HHHH. b. If each outcome is equally likely, what is the probability that all four coin tosses result in heads? Notice that the complement of “all four heads” is “at least one tail.” Using this information, compute the probability that there will be at least one tail out of the four coin tosses. 1. Suppose you roll a single fair die and note the number rolled. a. What is the sample space for a single roll of a fair die? Are the outcomes equally likely? b.
