Answer:

The Probability of not getting two consecutive reds is 0.9506

Step-by-step explanation:

Number of sections = 9

Number of red sections = 2

Number of blue sections = 3

Number of green sections = 4

Probability of getting two consecutive reds = \frac{2}{9} \times \frac{2}{9}=\frac{4}{81}

So,The Probability of not getting two consecutive reds =1- \frac{4}{81}=\frac{77}{81}=0.9506

Hence The Probability of not getting two consecutive reds is 0.9506
