the spinner shown has eight congruent sections. the spinner is spun 120 times. what is a reasonable prediction for the number of times the spinner will land on an even number?
Answer
Explanation:
Step1: Count even - numbered sections
There are 4 even - numbered sections (2, 8, 16) out of 8 total sections.
Step2: Calculate the probability of landing on an even number
The probability $P$ of landing on an even number is $\frac{4}{8}=\frac{1}{2}$.
Step3: Predict the number of times
Multiply the total number of spins by the probability. So, $120\times\frac{1}{2}=60$.
Answer:
60
