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 reds?
OP

Answer 1

The Probability of not getting two consecutive reds is 0.9506

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 =
`(2)/(9) * (2)/(9)=(4)/(81)`

So,The Probability of not getting two consecutive reds =
`1- (4)/(81)=(77)/(81)=0.9506`

Hence The Probability of not getting two consecutive reds is 0.9506
