Answer:
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%
