Q. If you spin the spinner

8

times, what is the best prediction possible for the number of times it will not land on blue?

\newline

Choices:

\newline

(A)

2

\newline

(B)

3

\newline

(C)

1

\newline

(D)

5

Calculate Probability: First, we need to know the probability of the spinner not landing on blue. Assume the spinner has $4$ equal sections, one of which is blue. The probability of not landing on blue is $3$ out of $4$ sections.
Find Expected Number: Next, to find the expected number of times it will not land on blue in $8$ spins, multiply the probability by the number of spins: $\frac{3}{4} \times 8$ .
Final Prediction: Calculate $\frac{3}{4} \times 8 = 6$ . So, the best prediction is that the spinner will not land on blue $6$ times out of $8$ spins.
