1
Q
What are mutually exclusive events
A
Events which cannot occur at the same time
2
Q
What are independent events
what formula represents this
A
If the occourance of one event does not effect the occourance of another event
P(AnB) = P(A) xP(B)

3
Q
What does P(AnB) represent
A
Intersection
4
Q
What does P(AuB) represent
A
A Or B
5
Q
What formula do you use for independent events
A
P(CnD) = P(C) x P(D)
P(B|A) = P(B)
6
Q
Formula can be used If A and B are said to be mutually exclusive
A
If A and B are said to be mutually exclusive events then the probability of an event A occurring or the probability of event B occurring that is P (a ∪ b) formula is given by P(A) + P(B), i.e., P (A Or B) = P(A) + P(B)
