The probability of any event is between one and o. What is the equation for this? - ANSWER For any event A, 0 ≤ P(A) ≤ 1.

The sum of all possible probabilities is___? - ANSWER 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. - ANSWER P(not A) = 1 - P(A)

In probability, "OR" means either one or the other or both. - ANSWER P(A or B) = P(event A occurs or event B occurs or both occur)

Two events that cannot occur at the same time are called - ANSWER disjoint or mutually exclusive

The Addition Rule for Disjoint Events: - ANSWER If A and B are disjoint events, then P(A or B) = P(A) + P(B).

P(A and B) = - ANSWER P(event A occurs and event B occurs)

The idea of disjoint events is - ANSWER is about whether or not it is possible for the events to occur at the same time

The idea of independent events is about - ANSWER whether or not the events affect each other in the sense that the occurrence of one event affects the probability of the occurrence of the other 1 / 2

If A and B Disjoint - ANSWER A and B can not be indepentdent

If A and B are two independent events (Multiplication Rule) - ANSWER P(A and B) =

P(A) * P(B).

if A, B and C are three independent events, - ANSWER P(A and B and C) = P(A) * P(B) * P(C)

The Complement Rule, - ANSWER P(A) = 1 - P(not A),

P(L) = 1 - P(not L) = 1 - P(not O1 and not O2 and not O3 and not O4 and not O5 and not O6 and not O7 and not O8 and not O9 and not O10). - ANSWER Applying the Multiplication rule:Now, using the multiplication rule, = 1 - (.56 * .56 * .56 * .56 * .56 * .56 *

.56 * .56 * .56 * .56) = 1 - .003 = .997.

P(at least one person chosen has blood type O) - ANSWER P((O and O) or (O and not

• or (not O and O)) = (.44 * .44) + (.44 * .56) + (.56 * .44) = .6864.

If A and B are disjoint events - - ANSWER P(A and B)= 0

The General Addition Rule states that for any two events, - ANSWER P(A or B) = P(A) + P(B) - P(A and B)

When each of two outcomes has two possible values (yes/no), - ANSWER there are four possible combinations altogether, which correspond to the four possible outcomes.

How do we build a two-way table of probabilities? - ANSWER Horizontally, A, not A and total, Vertically, B. not B and total
