Concept explainers

It simply refers to the likelihood of an event taking place whenever the occurrence of an event is uncertain. The probability of a single event can be calculated by dividing the number of successful trials of that event by the total number of trials.

Expected Value

When a large number of trials are performed for any random variable ‘X’, the predicted result is most likely the mean of all the outcomes for the random variable and it is known as expected value also known as expectation. The expected value, also known …

Probability Distributions

Understanding probability is necessary to know the probability distributions. In statistics, probability is how the uncertainty of an event is measured. This event can be anything. The most common examples include tossing a coin, rolling a die, or choosi…

Basic Probability

The simple definition of probability it is a chance of the occurrence of an event. It is defined in numerical form and the probability value is between 0 to 1. The probability value 0 indicates that there is no chance of that event occurring and the prob…

Textbook Question

Chapter 5, Problem 12P

RunningWithTheDevil.com created a web site to market running shoes and other running apparel. Management would like a special pop-up offer to appear for female web-site visitors and a different special pop-up offer to appear for male web-site visitors. From a sample of past web-site visitors, RunningWithTheDevil’s management learns that 60% of the visitors are male and 40% are female.

a. What is the probability that a current visitor to the web site is female?
b. Suppose that 30% of RunningWithTheDevil’s female visitors previously visited LetsRun.com and 10% of male customers previously visited LetsRun.com. If the current visitor to RunningWithTheDevil’s web site previously visited LetsRun.com, what is the revised probability that the current visitor is female? Should the RunningWithTheDevil’s web site display the special offer that appeals to female visitors or the special offer that appeals to male visitors?
