Q. If you spin the spinner

10

times, what is the best prediction possible for the number of times it will land on pink?

\newline

\newline

\_\_\_\_\_

times

Determine sections on spinner: Step $1$ : Determine the total number of sections on the spinner and the number of sections that are pink. Assume the spinner has $8$ sections, with $3$ sections being pink.
Calculate probability of pink: Step $2$ : Calculate the probability of the spinner landing on pink. Probability $P$ = Number of pink sections / Total number of sections = $\frac{3}{8}$ .
Predict spins landing on pink: Step $3$ : Predict the number of times the spinner will land on pink after $10$ spins. Expected number $= \text{Probability of pink} \times \text{Number of spins} = \frac{3}{8} \times 10 = 3.75$ . Since we can't have a fraction of a spin, we round to $4$ .
