 | Multiplication Rule (The “And” Rule)
 | For statistical independence events (where the occurrence of one event has no effect on
the probability of the occurrence of any other event.) |
| P(A and B) = P(A) X P(B) |
| E.g. Records of service requests at a shop has the following probabilities:
Daily Request Probability
5 0.3
6 0.7
Daily request is independent. What is the number that over a two day period the number of
request will be
a) 10, b) 11,
c) at least 11 requests?
