WGU Stats Module 7- Probability Questions And Answers Examples of Quantitative and Qualitative Probability - answerQualitative Description= impossible Quantitative Probability = 0% probability Qualitative Description= Unlikely Quantitative Probability = 1% to 30% probability Qualitative Description= As likely as unlikely Quantitative Probability = 40-60% Qualitative Description= likely Quantitative Probability = 70-99% Qualitative Description= certain Quantitative Probability = 100% experiment - answerthe procedure or situation in which the probability is being calculated example- rolling a dice, raining outcomes - answerthe possibilities of what can occur during the experiment, the results rolling a dice- 1,2,3,4,5,6 are outcomes event - answercomprised of 1 or more outcomes die landing on an uneven number is an event probability of an event - answerP(E)= probability of a certain event occuring if R= RAIN and the weatherman says there is a 40% chance of rain, then P(R)= .40 an experiment is fair if - answereach outcome is equally likely An experiment is the procedure to test the occurrence of an event. True or False? - answerFalse Correct. This is a false statement. An experiment is the procedure for which the probability of an event is calculated. set - answersimply a collection of unique elements. For example, a set of tree species is: oak, juniper, elm, maple. subsets - answerSet A is a subset* of set B , if every element in A is contained within B . For example: A={1,2,3} B={1,2,3,4,5} A is a subset of B , because every element in set A is contained within set B . empty set - answerhas no elements {} For example, let's say you wanted to list the days of the week that do not end in a y. There are none! Therefore, this is the empty set. In set notation, the empty set is written as a pair of brackets with nothing between them: union - answerThe union* of two sets is a collection of all of the elements listed in the sets. For example:
