event correct answers any collection of results or outcomes of a procedure simple event correct answers outcome or event that cannot be further broken down into simpler compounds Define Mutually Exclusive correct answers Events are disjoint. Events share no outcomes in common! P(A and B) = 0 Define Independence correct answers When two events are said to be independent of each other, what this means is that the probability that one event occurs in no way affects the probability of the o...

addition rule - a mathematical rule used to calculate the probability of the union of events alpha - The probability of rejecting the null hypothesis when, in reality, it is true. Alternative hypothesis - Designated H1, this hypothesis represents the opposite of the null hypothesis and holds true if the null hypothesis is found to be false. The alternative hypothesis always states the population parameter is <, not equal (=/), or > a specific value. bar chart - A chart that displays q...
