Question 1

Exponential probability distribution

Answer 1

A continuous probability distribution that is useful in computing probabilities for the time it takes to complete a task.

Question 2

Normal Probability Distribution

Answer 2

A continuous probability distribution. Its probability density function is bell shaped and determined by its mean μ and standard deviation σ.

Question 3

Probability Density Function

Answer 3

A function used to compute probabilities for a continuous random variable. The area under the graph of a probability density function over an interval represents probability.

Question 4

Standard Normal probability Distribution

Answer 4

A normal distribution with a mean of zero and a standard deviation of one.

Question 5

Uniform Probability Distribution

Answer 5

A continuous probability distribution for which the probability that the random variable will assume a value in any interval is the same for each interval of equal length.
