Problem

Use the spinner shown. It is equally probable that the pointer will land on any one of the eight regions. If the pointer lands on a borderline, spin again. If the pointer is spun three times, find the probability that it will land on blue and then yellow and then purple

Final Answer: The probability that the spinner will land on blue and then yellow and then purple is \(\boxed{0.001953125}\).

Steps

Step 1 :The spinner has 8 regions and it is equally probable that the pointer will land on any one of the regions. Therefore, the probability of landing on any one color is \(\frac{1}{8}\).

Step 2 :Since the pointer is spun three times, and we want it to land on blue, then yellow, then purple, we multiply the probabilities of these three independent events.

Step 3 :The probability of landing on blue is \(0.125\), the probability of landing on yellow is \(0.125\), and the probability of landing on purple is \(0.125\).

Step 4 :The probability of the sequence of landing on blue, then yellow, then purple is \(0.125 \times 0.125 \times 0.125 = 0.001953125\).

Step 5 :Final Answer: The probability that the spinner will land on blue and then yellow and then purple is \(\boxed{0.001953125}\).
