if you spin the spinner 48 times, what is the best prediction possible for the number of times it will land on blue or yellow? times submit
Answer
Explanation:
Step1: Determine the probability of landing on blue or yellow
Assume the spinner is divided into 8 equal - sized sections and 3 are blue and 2 are yellow. So there are 3 + 2=5 favorable sections out of 8. The probability $P$ of landing on blue or yellow is $P=\frac{3 + 2}{8}=\frac{5}{8}$.
Step2: Calculate the expected number of times
We spin the spinner $n = 48$ times. The expected number of times $E$ it lands on blue or yellow is given by the formula $E=n\times P$. Substitute $n = 48$ and $P=\frac{5}{8}$ into the formula: $E = 48\times\frac{5}{8}$. $48\times\frac{5}{8}=\frac{48\times5}{8}=\frac{240}{8}=30$.
