Question

URGANT NEEDED RIGHT NOW MUCH APPRECIATED:

A fair spinner has 9 equal sections: 3 red, 4 blue and 2 green. 
It is spun twice. 
What is the probability of getting blue both times?​

Answer 1

Probability of getting blue both times =
`(16)/(81)`

Explanation:

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

It is spun twice.

We have to find the probability of getting blue both times?.

For both times , the probability of getting blue is the same.

Probability =
`(number of favorable cases)/(total number of cases)`

The number of favorable cases for blue = 4

Total number of cases = 9

Hence the probability =
`(4)/(9)`

We have to get it two times so final probability =
`(4)/(9)* (4)/(9) = (16)/(81)`
