Determine the number of outcomes in the event. Then decide whether the event is a simple event or not. Explain your reasoning.

A computer is used to randomly select a number between 1 and 1000. Event A is selecting a number greater than 600.

A.600; Not a simple event because it is an event that consists of more than a single outcome.

B.400; Simple event because only one number is selected.

C.400; Not a simple event because it is an event that consists of more than a single outcome.

D. 1; Simple event because it is an event that consists of a single outcome.

Determine the number of outcomes in the event. Then decide whether the event is a simple event or not. Explain your reasoning.

You randomly select a computer from a batch of 50 which contains 3 defective computers. Event B is selecting a defective computer.

A. 3; Not a simple event because it is an event that consists of more than a single outcome.

B. 50; Not a simple event because it is an event that consists of more than a single outcome.

C. 1; Simple event because it is an event that consists of only one type of computer.

D. 3; Simple event because it is an event that consists of only one type of computer.

Provide an appropriate response. Use the Standard Normal Table to find the probability.

An airline knows from experience that the distribution of the number of suitcases that get lost each week on a certain route is approximately normal with

mu

equals

15.5

and

sigma

equals

3.6.

What is the probability that during a given week the airline will lose more than 20 suitcases?

A.0.8944

B.0.3944

C.0.1056

D.0.4040

You are trying to decide whether to play a carnival game that costs $1.50 to play. The game consists of rolling 3 fair dice. If the number 1 comes up at all, you get your money back, and get $1 for each time it comes up. So for example if it came up twice, your profit would be $2. The table below gives the probability of each value for the random variable X, where: X = profit from playing the...
