Problem number 5#

Eleven of the 50 digital recorders (DVRs) in an inventory are known to be defective. What is the probability you randomly select an item that is not defective?

The probability is = 1-(11/50) = 39/50 =0.78(Do not round).

problem # 6

Identify the sample space of the probability experiment and determine the number of outcomes in the sample space. Randomly choosing an odd number between 1 and 9, inclusive The sample space is (Use a comma to separate answers as needed. Use ascending order.) so there are ---- outcomes in the sample space.

Sample space is: {1,3,5,7,9} so there are 5 outcomes in the sample space.

problem#7.

A software company is hiring for two positions: a software development engineer and a sales operations manager. How many ways can these positions be filled if there are 19 people applying for the engineering position and 18 people applying for the managerial position?

The position can be filled in 19 X 18 = 342 ways.

problem#9.

Consider a company that selects employees for random drug tests. The company uses a computer to randomly select employee’s numbers that range from 1 to 5839. Find the probability of selecting a number less than 1000. Find the probability of selecting a number greater than 1000.

The probability of selecting a number less than 1000 is (999/5839) = 0.171(Round to three decimal places as needed.)

The probability of selecting a number greater than 1000 is (4839/5839) = 0.823(Round to three decimal places as needed.)

problem #10.

Consider a company that selects employees for random drug tests. The company uses computer to randomly select employee numbers that range from 1 to 6282. Find the probability of selecting a number less than 1000. Find the probability of selecting a number greater than 1000.

The probability of selecting a number less than 1000 is = 999/6282 = 0.159 (round to three decimal places as needed.)

The probability of selecting a number greater than 1000 is =...
