Abag has 4 green marbles and 8 red marbles. half of the red marbles are made of plastic. a marble is selected at random from the bag. what is the probability that it is red, plastic marble? write answer as a fraction.

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.

answer: just subtact the units and then add the non negative : happy to
