1. A surgical procedure requires choosing among four alternative methodologies. The first can result in five possible outcomes, the second can result in three possible outcomes, and the remaining methodologies can each result in two possible outcomes. What is the total number of outcomes possible?

2. An experiment requires a sequence of three steps. The first step can result in three possible outcomes, the second in four possible outcomes, and the third in six possible outcomes. What is the total number of outcomes possible?

3. For the given decision algorithm, find how many outcomes are possible. HINT [See Example 1.]

Step 1: Step 2:
    Alternative 1: 1 outcome     Alternative 1: 2 outcomes
    Alternative 2: 2 outcomes          Alternative 2: 5 outcomes
    Alternative 3: 1 outcome

Homework Answers

Answer #1

1) Number of Total Outcomes = Number of first possible outcomes + Number of second possible outcomes + Number of outcomes for remaining methodologies = 5 + 3 + 2 + 2 + 2 = 14 outcomes

2) Total Number of outcomes = First Step outcomes * Second step outcomes * Third step outcomes = 3 * 4 * 6 = 72 outcomes

3) Alternative 1 = 1 * 2 = 2

Alternative 2 = 2 * 5 = 10

Alternative 3 = 3

Total outcomes = 2 + 10 + 3 = 15

1. There are five wires which need to be attached to a circuit board. A robotic device will attach the wires. The wires can be attached in any order, and the production manager wishes to determine which order would be fastest for the robot to use. Use the multiplication rule of counting to determine the number of possible sequences of assembly that must be tested. (Hint: There are five choices for the first wire, four for the second wire, three...

Base Conversion One algorithm for converting a base 10 number to another base b involves repeatedly dividing by b. Each time a division is performed the remainder and quotient are saved. At each step, the dividend is the quotient from the preceding step; the divisor is always b. The algorithm stops when the quotient is 0. The number in the new base is the sequence of remainders in reverse order (the last one computed goes first; the first one goes...
