The probably of picking a red marble out of a bag with 3 green, 5 blue, 2 red, and 6 yellow marbles.

Hello there!

The probability of picking a red marble out of a bag of 3 green, 5 blue, 2 red, and 6 yellow marbles is 2/14.

There are 14 marbles that we don't want and 2 marbles that we want. That's why it would be 2/14.

Simply 2/14 to 1/7.

Therefore, the probability of picking a red marble is 1/7.

your answer would be b

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
