P( ext{event}) = rac{ ext{favorable}}{ ext{total}}

When all outcomes are equally likely

When order of items matters

When order doesn't matter

Find total number of possible outcomes (denominator)

Count favorable outcomes (numerator)

Multiply the numbers together

Add together the different cases

$P( ext{at least one}) = 1 - P( ext{none})$

Between 0 and 1
