"not" - -Let A = Bob wears a black suit. Let B = Bob wears black shoes. We can now use this table to define some important categories in probability. In the table below, "not A" is illustrated in orange. Remember A = "Bob wears a black suit." "Not A " is Bob wears a blue or brown suit. The color of the shoes is irrelevant. In our Bob example, "not B " is not wearing black shoes. This is again illustrated in orange in the table below. "not" venn diagram - -"Not A " in our real...

The probability of any event is between one and o. What is the equation for this? - -For any event A, 0 ≤ P(A) ≤ 1. The sum of all possible probabilities is___? - -One, the equation is :P(S) = 1 What is the complement rule? or the probability that an event does not occur is 1 minus the probability that it does occur. - -P(not A) = 1 - P(A) In probability, "OR" means either one or the other or both. - -P(A or B) = P(event A occurs or event B occurs or both occur) Two events that cann...

In a standard 52-card deck, where each card is assigned a numeric value, the mean of the 52 cards is 7.0 with a standard deviation of 3.742. To test if a representative sample can be attained, the deck is shuffled and 13 cards are randomly drawn, one at a time. Each card is recorded and then returned randomly to the deck before the next card is drawn. This process of drawing 13 random cards is repeated a total of 20 times, and the mean and standard deviation of each round is computed. Which...
