University Of Venda
Mat 1243/1643
Second Semester 2022
, Topic: Probability
Objectives:
z Identify the Sample Space of a Probability event.
z Determine if two Events are Mutually Exclusive
z Determine if two Events are independent.
z Calculate the Basic Probability using formulas, tree
diagram and Contingency Table.
z Calculate the total numbers of events in a given sample
space, using the concepts of permutations and
combinations.
, Introduction
> Some events in life are impossible; other events are quite
certain to happen.
> For example, it is impossible for a human being to live for
1000 years. Thus, we say that the probability of a human
being living for 1000 years is 0
> On the other hand it is quite certain that all of us will die
someday. Thus, we say that the probability that all of us
will die is 1.
> Using the letter P to stand for probability we can write.
P (a human will live for 1000 years) = 0
and
P (all of us will die someday) = 1
