Update) Questions and Verified Answers|
100% Correct| Grade A
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
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
