Define Experiment |
It is any process, which generates well-defined outcomes. |
|
|
Define Probability |
Probability is a ratio measuring the likelihood or chance that an event will happen. |
|
|
Define P(A or B) |
P(A or B) = P(A) + P(B) – P(A and B) |
|
|
Define a mutually exclusive event |
If an event A can occur or an event B can occur but not both A and B can occur, then the two events A and B are said to be mutually exclusive. It has no intersection |
|
|
When A and B are mutually exclusive the formula is |
P (A or B) = P (AUB) = P(A)+P(B) |
|
|
Define Conditional probability |
It is the probability of A, given that B has already occurred is written P (A / B) |
|
|
Conditional Probability Formula |
|
|
|
If the intersection in a conditional probability is 0 then |
Everything else is 0 |
|
|
Define Independent events |
If either of the events A and B can occur without being affected by the other, then the two events are independent. |
|
|
Multiplication law for independent events |
