Q

A
Event A is given condition B.
2
Q
How to probably speak a conditional probability?
A
Probability of A that is restricted to B.
3
Q
What is the sample space of P(A|B)?
A
B
4
Q
Two events are independent is when?
A
One event does not change the probability of another. P(A|B) = P(A) and P(B|A) = P(B). Otherwise, dependent
5
Q
Multiplication rule given events A and B?
A
Probability that both events will occur is unconditional probability of event B times the conditional probability of event A.
6
Q
If you have independent events A and B, then P(A|B)?
A
P(A)
