Similarly, for the rules of addition, there are two to choose from.You use the rule P(A or B) = P(A) P(B) if the events are mutually exclusive.

The word statistics may bring to mind polls and surveys, or facts and figures in a newspaper article.
But statistics is more than just a bunch of numbers: Statistics is a problem-solving process that seeks answers to questions through data.
So in essence, you want the probability of her choosing these two flavors.
Determine whether the events are mutually exclusive or independent if appropriate.
You obtain data by measuring something, so your measurement methods must be chosen with care.
Sampling is one way to collect data; experimentation is another.After you analyze your data, you must interpret it in order to provide an answer -- or answers -- to the original question.This four-step process for solving statistical problems is the foundation of all the activities in this course.Breaking down the percentages into decimals will yield 0.60 x 0.70, found by dividing both percentages by 100. Converting the answer back to a percentage by multiplying by 100 will yield 42 percent. Contributing to e How, she is also a software engineer and adjunct instructor of statistics and computer information systems.Friesen holds a Master of Science in engineering management and a certificate in financial engineering, as well as Bachelor of Science degrees in applied mathematics and computer science from the Missouri University of Science and Technology.By asking and answering statistical questions, we can learn more about the world around us.Statistics is used every day to help us gain insight into questions that affect our lives: Is our population growing or shrinking? Will eating more fruits and vegetables really make us live longer?Most probability questions are word problems, which require you to set up the problem and break down the information given to solve.The process to solve the problem is rarely straightforward and takes practice to perfect.It's important to ask a question carefully, with an understanding of the data you will use to find your answer.Collecting data to help answer the question is an important step in the process.
