A
P(Event)=desired outcome/total outcomes
2
Q
sample space definition
A
set of all possible outcomes
2
Q
mutually exclusive events
A
can’t happen at the same time
∴ P(A and B)=0
P(A or B)=P(A)+P(B)
2
Q
independent events
A
the probability of one event happening x affect the probability of the other happening
∴ P(A and B)=P(A)xP(B)
