Step-by-Probability of it turning out the way you want =
(number of different outcomes that you like)
divided by
(total number of ways it can possibly turn out) .
Total number of ways the spinner can land = (1 + 4 + 6 + 1) = 12
Number of ways you'll be happy with = (yellow + red) = (6 + 4) = 10
Probability of a spin that you like = 10/12 = 5/6 = (83 and 1/3) % .
If the spinner is honest, well-balanced, and doesn't stick or scrape,
and nobody blows or sits on it while it's spinning, then you'll predict
that 5/6 of the spins will turn out in ways that you like.
5/6 of 96 = 80 spins
