    4. The Probability Calculus- Restricted Disjunction Rule To calculate the probability that either of two events will occur when the events are mutually exclusive, use the restricted disjunction rule. Two events are mutually exclusive if they cannot both occur at the same time. To calculate the probability of either of two mutually exclusive events (A and B) occurring, according to the restricted disjunction rule, use the following formula P(A or B) P(A)P(B) This formula tells you that the probability of...
