A Chance Is a Share of Cases
Captions available
The idea
A chance is a fraction between 0 and 1: the share of relevant cases in which a thing happens — 0 for never, 1 for always.
In practice
A raffle drum holds 1,000 tickets and you bought 250: your chance is 250 out of 1,000 — 0.25.
Where people slip
A count means nothing until its denominator is known — 250 tickets of how many?
