if you spin the spinner 8 times, what is the best prediction possible for the number of times it will land on blue? times
Answer
Explanation:
Step1: Calculate probability of landing on blue
The spinner is divided into 8 equal - sized sections and 2 of them are blue. So the probability $P$ of landing on blue in a single spin is $P=\frac{2}{8}=\frac{1}{4}$.
Step2: Predict number of times for 8 spins
To find the best prediction for the number of times it will land on blue in 8 spins, we multiply the probability of landing on blue in a single spin by the number of spins. Let $n$ be the number of times it lands on blue. Then $n = P\times8$. Substituting $P=\frac{1}{4}$ into the formula, we get $n=\frac{1}{4}\times8 = 2$.
