binomial probability distribution

binomial probability distribution

P=(nCk)(p↑k)(q↑n-k)

probability of 2 things

P(A|B)=P(A and B)/P(A)

test for independence

If P(A|B)=P(A), then A and B are independent;

If P(B|A)-P(B), then A and B are independent

(over B)

z-score formula

z=(x-µ)/σ

expected value/weighted average formula?

p(b)xfreq+p(a)xfreq…
