A bag contains 5 red marbles 4 white marbles and 3 blue marbles. You draw a marble and replace it two times. Find each probability

8 is the probablitiy

Step-by-step explanation:

4+5=9 -1 = 8

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

47 - 90 = 43

43 - 180 = x

x = 137
