Chapter 8-Probability and Poisson Distribution Quiz

A local bakery sells an average of 5 cakes each day. What is the probability of selling 40 cakes in a week?

• 0.45%

• 4.5%

• 45%

• There is not enough information to solve the problem.

A Poisson distribution can be used to find the probability of an event related to which of the following?

• Time

• Distance

• Area

• All of the answers are correct.

To use a Poisson distribution, each successful event must be what?

• Independent

• Dependent

• Rare

• Constant

In a Poisson distribution, the likelihood of each successful event must do what over any interval?

• Decrease

• Remain constant

• Increase

• Change

In the Poisson formula, what does the variable x represent?

• The expected value

• The unknown

• The number of successful events

• Euler's constant

Which graph represents a continuous, uniform probability distribution?

• Option 1

• Option 2

• Option 3

• Option 4

What makes a probability distribution uniform?

• When all possible outcomes have an equal chance, or probability, of occurring

• When the outcomes are continuous

• When the graph is a straight line with any angle

• When the outcomes are discrete

What is the difference between a discrete distribution and a continuous distribution?

• Discrete means the outcomes are very hard to find, while continuous means the outcomes are obvious

• Discrete means the outcomes are distinct and finite within a range, while continuous means that there are infinite outcomes within a range

• Continuous means the outcomes are random, while discrete means the outcomes are determined

• Continuous and discrete are the same

Graphing the probability of getting heads or tails on consecutive flip of a coin is which of the following type of distribution?

• Discrete and continuous

• Continuous and uniform

• Continuous and non-uniform

• Discrete and uniform

Which of the following is NOT a uniform distribution?

• Option 1

• Option 2

• Option 3

• Option 4
