Chapter 1
Probability p(x) = lim (N -> inf) n0/ n
Independent (joint probability) vs Dependent (conditional
probability)
P of A or B / P of A and B
for mutually exclusive events (OR) : p(A) + p(B)
for independent events (AND): p(A)p(B)
for all events (OR): p(A) + p(B) - p(A)p(B) (for mutually
exclusive events where p(A)p(B) = 0)
for dependent events (AND): p(A)p(B|A)
probability distribution: <P> = sigma pi*xi
xi = value, and pi = probability
A = {AA, KK, QQ, JJ, AKo, AKs}
B = {AA, KK, QQ}
<A, B> : expectation for playing the distribution A vs
distribution B
<A, AA|B> : expectation for playing the distribution A against
the hand AA taken from the distribution B.
<AA|A, AA|B> : expectation for playing AA from A against AA from
B
<A, B> = p(AA)<A, AA|B> + p(KK)<A, KK|B> + p(QQ)<A, QQ|B>
Key concepts:
- the probability of an outcome of an event is the ratio of that
outcome's occurence over an arbitrarily large number of trials
of that event.
- a probability distribution is a pairing of a list of complete
and mutually exclusive outcomes of an event with their
corresponding probabilities
- the EV of a valued probability distribution is the sum of the
probabilities of the outcomes times their probabilities
- EV is additive
- if each outcome of a probability distribution is mapped to
numerical values, the expected value of the distribution is the
summation of the products of probabilities and outcomes
- a mathematical approach to poker is concerned primarily with
the maximization of EV
