## Thinking Mathematically (6th Edition)

P(E) = $\frac{no.\ of\ outcomes\ in\ favor}{Total\ no.\ of\ outcomes}$ It is equally probable that the pointer will land on any one of the ten colored regions, and we spin again if we land on a borderline. There are 10 total regions. E: A region that is red and blue. There are no regions that are both red and blue. Favorable outcomes= {⌀} P(E) = $\frac{0}{10}$ = 0
