Step-by-step explanation:

Given  : A bag contains only red marbles and blue marbles. there are 6 marbles in the bag. the bag contains twice as many blue marbles as red marbles. nadia takes one marble from the bag without looking.

To find :  the probability that the marble is blue .

Solution : We have given

Total marble in beg = 6

Let the red marble  = x

Blue = 2x .

So, x + 2x = 6.

3x = 6

On subtracting both sides by 3

x = 2.

Red marble = 2

Blue marbles are 4.

Probability of getting blue = .

Probability of getting blue = .

Probability of getting blue = .

Therefore, Probability of getting blue = .
