A bag contains 4 red marbles, 5 blue marbles, and 3 green marbles. Two marbles are picked at random. What is the fractional probability that 2 red marbles are picked if the first marble was returned before the second was chosen? stow imformation

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%

the answer would be c ≈ 18.852*3.14= 6.286.28*3=18.85
