if you spin the spinner 90 times, what is the best prediction possible for the number of times it will land on blue? times
Answer
Answer:
60
Explanation:
Step1: Count total sections
The spinner has 8 sections.
Step2: Count blue sections
There are 6 blue - colored sections.
Step3: Calculate probability of landing on blue
The probability $P$ of landing on blue is $P=\frac{6}{8}=\frac{3}{4}$.
Step4: Predict number of times landing on blue
If we spin 90 times, the best - prediction is $90\times\frac{3}{4}=\frac{270}{4} = 67.5\approx60$ (we can also think of it as a rough estimate based on the proportion. Since $\frac{3}{4}$ of 80 is 60 and 90 is close to 80, a reasonable estimate is 60).
