can you write the mathematical expression for the probability of an event e occurring. Odds change exponentially based on the number of events occurring. Where A and B are events PAB is the conditional probability that event A occurs given that event B has already occurred PBA has the same meaning but with the roles of A and B reversed and PA and PB are the marginal probabilities of event A and event B occurring respectively.

A plot of the PDF and the CDF of an exponential random variable is shown in Figure 39The parameter b is related to the width of the PDF and the PDF has a peak value of 1b which occurs at x 0. If you are uncertain and would use the expression I really dont know the event may or may not occur with a probability of 50. Applies mathematical processes to determine the number of elements in a finite sample space and compute the probability of an event.
The probability of the intersection of A and B may be written pA B.
Joint Probability is a statistical measure of two or more events happening at the same time ie PA B C The probability of event A B and C occurring. Mathematical definitions can often feel too abstract and scary so lets try to understand this. Larger numbers indicate greater likelihood. The probability of an event is a number between 0 and 1 where roughly speaking 0 indicates impossibility of the event and 1 indicates certainty.
