The basic multiplication rule is used for finding P(A and B), the probability that event A occurs in a first trial and event B occurs in a second trial. If the outcome of the first event A somehow affects the probability of the second event B, it is important to ___________the probability of B to reflect the ____________ of event A.

Pew Research revealed 92% of adults know twitter. 5 adults were randomly chosen. What is the probability Exactly 3 adults know twitter. Note: 5C3 means 5 combination 3 where order is not important

The probability that events A or B will occur, P(A or B), is given by P(A or B) = P(A) + P(B) P(A and B). If events A and B are mutually exclusive, then the rule can be simplified to ___________. It is because __________

The frequency distribution shows volumes of sales and the number of months in which a sales representative reached each sales level during the past three years. Using this sales pattern, find the probability that the sales representative will sell between 25,000 and 74,999 next month  

We found for families with two children, the mean number of girls is 1.0 and the standard deviation is 0.7 girls. Use those values to find the maximum and minimum usual values for the number of girls. Will 2.5 be unusual?

A student decided not to study for his Statistics test consisting of 12 questions. He said I will probably do well, since its multiple choice and I have ¼ chance of getting the answer right. Without reading the test he decides to bubble in at random. What is the probability he gets all of the questions right? The first 10 right? 4 right in total?

Intuitive Addition Rule. To find P(A or B), find the sum of the __________ event A can occur and the number of ways event B can occur, adding in such a way that ____________ is counted only ______. P(A or B) is equal to that sum, divided by the total number of outcomes in the sample space.
