Relative Frequency (HSC SSCE Mathematics Advanced): Flashcards

$f_r = \frac{f}{n}$ where $f$ = frequency, $n$ = total trials

Experimental probabilities

$E(X) = \sum x \cdot p(x)$

$\text{Var}(X) = E(X^2) - \mu^2$

$\sigma = \sqrt{\text{Var}(X)}$

$F(x) = P(X \leq x)$

Always increases from 0 to 1 (monotonic increase)

Equals 1

Ten equal parts
