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

Textbook Question

Chapter 6.2, Problem 6.31E

Airlines book more seats than arc actually available, then “hump” would-be passengers whenever more people show up than there are seats. Through the first quarter of 2009, the rate at which passengers were humped was 1.40 per 1000 passengers. Assuming that, on average, the probability of any given passenger being bumped is 1.40/1000, or 0.00140: Source: U.S. Bureai of Transportaton Statistcs, June 2009.

a. Emily is flying nonstop to visit Besco, Inc., for a job interview. What is the probability that she will be

bumped?

b. Ten members of the Besco board of directors will be flying nonstop to the firm’s annual meeting, and their flights are independent of each other. What is the probability that at least one of them will be bumped?

c. Besco sales personnel made a total of 220 nonstop flights last year, and they experienced a total of four bumpings. Could the company’s experience be cons idered as very unusual?
