The _ event A occurring are the ratio P(A)/(P(A-)

Quesiton : The _ event A occurring are the ratio P(A)/(P(A-)

Answer: addition rule

The _ event A occurring are the ratio P(A)/(P(A-) A _ is any event combining two or more simple events. Describe what the notation P(BlA) represents. The probability of event B occurring given that event A has already occurred. of event A occurring are the ratio P(A[bar])/P(A) which is the reciprocal of the actual odds against the event. If the odds against A are a:b then the odds in favor of A are b:a. Odds against event = P ( event fails to occur )/ P ( event occurs) = P (failure)/ P (success) The odds in favor of an event are expressed as a ratio of the probability that the event will occur to the ... The odds of an event of interest occurring is defined by odds = p /(1- p ) where p is the probability of the event occurring . So if p =0.1 the odds are equal to 0.1/0.9=0.111 (recurring). So here the probability (0.1) and the odds (0.111) are quite similar. event A occurring are the ratio P ( A)/P (A) usually expressed in the form of a:b (or “a to b”) where a and b are integers having no common factors. The actual odds in favor of event A occurring are the ratio P ( A)/P (A) which is the reciprocal of the actual odds against the event . occur then P (Ec)=1− P (E)and P (E)=1− P (Ec). • Odds - Odds are another way of representing the probability of an event and are given as a ratio of the number of times the event will occur to the number of times the event will not occur in the long run. If P(A|B) = P(A) then events A and B are said to be independent: in such a case having knowledge about either event does not change our knowledge about the other event. Also in general P ( A | B ) (the conditional probability of A given B) is not equal to P ( B | A ). Definitions – Page 145 The actual odds against event A occurring are the ratio P ( A)/P (A) usually expressed in the form a:b (or “a to b”) where a and b are integers having no common factors (reduced). How to find probability of events . Again the probability of a single event is called it's P -value and you can express it as such:. The probability of A = P (A) The probability of B = P (B) The basic definition of probability is the ratio of the number of a chosen outcome to the total number of all possible outcomes. [latex] P (\text{ event })=\frac{\text{favorable outcomes}}{\text{total outcomes}}\\[/latex] Sometimes people express the likelihood of events in terms of odds rather than probabilities. The odds of an event occurring are equal to the ratio of favorable outcomes to unfavorable outcomes .
