Expert Solution
An event A can happen in n ways and another event B can happen in m ways. The events A and B are non-overlapping.
Multiplication Principle
“If one event can occur in m ways and a second event with no common outcomes can occur in n ways after the first event has occurred, then the two events can occur in m × n ways.”
Use the multiplication principle,
Total number of ways event ‘A and B’ can occur will be equal to the product of the number of ways the event A can occur and the number of ways the event B can occur.
That is,
Number of ways event ‘A and B’ can occur = number of ways event A can occur × number of ways event B can occur
As,
The event A can occur in n ways and event B can occur in m ways. Hence the event A and B both simultaneously can occur in n × m ways.
The event A can occur in n ways and event B can occur in m ways. Hence the event A and B both simultaneously can occur in n × m ways.
