In the case where A and B are mutually exclusive events, P(A ∩ B) = 0. The intersection of events A and B, written as P(A ∩ B) or P(A AND B) is the joint probability of at least two events, shown below in a Venn diagram. if P(A) = 0.65, P(B) does not necessarily have to equal 0.35, and can equal 0.30 or some other number. Any P(B') would be calculated in the same manner, and it is worth noting that in the calculator above, can be independent i.e. Given this scenario, there is, therefore, a 35% chance that Bob does his homework. If, for example, P(A) = 0.65 represents the probability that Bob does not do his homework, his teacher Sally can predict the probability that Bob does his homework as follows: Given a probability A, denoted by P(A), it is simple to calculate the complement, or the probability that the event described by P(A) does not occur, P(A'). The calculator provided computes the probability that an event A or B does not occur, the probability A and/or B occur when they are not mutually exclusive, the probability that both event A and B occur, and the probability that either event A or event B occurs, but not both. This is further affected by whether the events being studied are independent, mutually exclusive, or conditional, among other things. In its most general case, probability can be defined numerically as the number of desired outcomes divided by the total number of outcomes. It follows that the higher the probability of an event, the more certain it is that the event will occur. It is quantified as a number between 0 and 1, with 1 signifying certainty, and 0 signifying that the event cannot occur. Probability is the measure of the likelihood of an event occurring.
