State
The weighted average of uncertain outcomes multiplies each outcome by its chance and adds the results — the number a repeated gamble settles toward.
Show
A street vendor: rain, chance 0.3, pays 90; dry pays 20 — the average is 27 plus 14: 41.
Watch for
No single day yields 41 — the number is a long-run rate, not a forecast of tomorrow.
