if you spin the spinner 10 times, what is the best prediction possible for the number of times it will land on blue? times

Answer

Explanation:

Step1: Determine blue - section proportion

The spinner is divided into 8 equal sections and 1 is blue. So the probability of landing on blue in one spin is $p=\frac{1}{8}$.

Step2: Calculate expected number

We spin 10 times. The expected number of times landing on blue $E = n\times p$, where $n = 10$ and $p=\frac{1}{8}$. So $E=10\times\frac{1}{8}=\frac{10}{8} = 1.25$.

Answer:

1.25
