Possibilities Multiply
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
When each step offers b choices and a plan is d steps deep, the number of distinct plans is b multiplied by itself d times — b to the power d.
Show
Three starters, four mains, two desserts: 3 × 4 × 2 = 24 complete dinners.
Watch for
The power is not b times d — three choices over sixteen steps is forty-three million plans, not forty-eight.
