13275344 File Edt View Favenites Toels Help There are six wires which need to be attached to a circuit board. which order would be fastest for the robet to use. Use the of choices for the first wire, five for the second wire, four for the third wire, etc.) A robotic device will attach the wires. The wires can be attached in any order, and the production manager wishes to determine mutiplication ule of counting to determine the number of possible sequences of assembly that must be tested. (Mint: There are six Nood Help? Noles Ask Your Barbara is a research biologist for Green Carpet Lawns. She is studying the effects of fertilizer type, temperature at time of application, and water treatment after application. She has two fertilicer types, four temperature zones, and six water treatments to test. Determine the number of different lawn plots she needs in order to test each fertilizer type, temperature range, and water Need Help? o -0 points You toss a pair of dice Determine the number of possible pairs of outcomes. (Recall that there are six possible outcomes for each de.) ) There are three even numbers on each die. How many outcomes are possible with even numbers appearing on each die? (c) Probability extension: What is the probability that both dice will show an even number? (Round your answer to two decimal places.)

Explanation / Answer

Question 2 : Number of possible sequences of assepmly = there are 6 choices for first wire and so on

= 6! = 6 * 5 * 4 * 3 * 2 * 1 = 720

Question 3 : Number of different lawn plots to test four temperature zones, two fertiliser types and six water treatments.

Number of different lawn plots = 2 * 4 * 6 = 48

Qustion 4 Tossed a pair of dice .

(a) Number of Possible pair of outcomes = 6 * 6 = 36

(B) Even number appearing on each die = 3 * 3 = 9

(C) Probability that both dice will show even number = 9/36 = 0.25
