Question

A fair spinner has 9 equal sections: 2 red, 3 blue and 4 green.

It is spun twice.
What is the probability of not getting two consecutive blues?

Answer 1

8/9 or 88.89%

Explanation:

Spinner has a total of 9 sections.

These sections are;

2 red, 3 blue and 4 green.

Now, probability of getting blue at one spin = 3/9 = 1/3

Probability of getting 2 consecutive blues = ⅓ × ⅓ = 1/9

Probability of not getting 2 consecutive blues = 1 - probability of getting 2 consecutive blues = 1 - 1/9 = 8/9 or in percentage 8/9 × 100% = 88.89%
