if you spin the spinner 63 times, what is the best prediction possible for the number of times it will not land on yellow? times
Answer
Explanation:
Step1: Count total sections and yellow sections
Assume the spinner has 8 equal - sized sections and 2 are yellow.
Step2: Calculate probability of not landing on yellow
The probability of landing on yellow is $P(\text{yellow})=\frac{2}{8}=\frac{1}{4}$. So the probability of not landing on yellow is $P(\text{not yellow}) = 1-\frac{1}{4}=\frac{3}{4}$.
Step3: Predict number of non - yellow landings
Multiply the total number of spins by the probability of not landing on yellow. If we spin 63 times, the number of times it will not land on yellow is $63\times\frac{3}{4}=\frac{189}{4}=47.25\approx47$ (rounded to the nearest whole number).
Answer:
47
