      The notation P(A, given B) denotes the probability that event A will occur, given that event B has occurred. We call this conditional probability. *** View Example #'s 3 & 4 (text p.199 - 201). Probability of A or B. The condition A or B is satisfied by any of the following: 1) Any outcome of A occurs. 2) Any outcome of B occurs.

      Where P(B|A) is called the conditional probability of B given A, read as Probability of B given A. If this were a course on probability, we’d spend a week or so on conditional probability. We won’t pursue this general case here, however. Two special cases: A. A and B are mutually exclusive.

      Probability. Probability is the chance that something will happen - how likely it is that some event will happen over the long run.Sometimes you can measure a probability with a number: "10% chance of rain", or you can use words such as impossible, unlikely, possible, even chance, likely and certain.
