P(A)
the probability that A happens
1 of 12
P(A’)
the probability that A does not happen
2 of 12
(AᴖB)
the probability that both A and B happen
3 of 12
(AᴗB)
the probability that either A or B or both happen
4 of 12
P(A l B)
the probability that A happens, given that B has happened
5 of 12
A and B are independent if you can show:
- P(AᴖB) = P(A) x P(B)
6 of 12
A and B are mutually exclusive if you can show:
- P(AᴖB) = 0
