Relative and Expected Frequency (HSC SSCE Mathematics Standard): Flashcards

Experimental probability based on actual observed results

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

Fraction, decimal, or percentage

Mathematical model representing a real experiment

When real experiments are too costly or time-consuming

Predicted number of occurrences based on probability theory

$np$ where $n$ = trials, $p$ = probability

More trials = actual results closer to expected frequency

$f$ = frequency of event, $n$ = total trials

$n$ = trials, $p$ = probability
