Answer:

7/9 or ~77.7778% or 0.777778

Step-by-step explanation:

First you need to find the total amount or marbles.

  • 8+4+6=18

Next, find the sum of just the blue and red marbles.

  • 8+6=14

Now, find the probability by dividing or simplifying the number of blue and red by the total.

  • 14/18= 7/9 OR ~0.777778
