A jar contains 3 blue marbles, 6 red marbles, 1 green marble, and 2 black marbles. A marble is chosen at random from the jar and replaced. Then another marble is chosen at random. Find the probability of the first marble being red and the second marble being green.

0.0416

Step-by-step explanation:

A jar contains 3 blue marbles, 6 red marbles, 1 green marble, and 2 black marbles

Total possible outcomes will be:

3+6+1+2 = 12 marbles

Probability of picking red

P(red) = 6/12 = 0.5

P(green) = 1/12 = 0.0833

probability of the first marble being red and the second marble being green will be

P(red) ×P(green) = 0.5×0.0833

= 0.0416
