Hello There

Answer: 14/24


To find this we need to add together all of the marbles

6 + 8 + 5 + 5 = 24

This number will go on the bottom of our fraction

----
24

To find the top we simply add together the red a blue marbles

6 + 8 = 14

So 14 goes on top of the fraction

14
----
24

Our final answer is 14/24

I hope this helps

The probability is 6/24 for red marble and 8/24 for the blue
6+8+5+5 = 24 this is the total number of marbles
Because the probability would be the number of marbles divided by the total number of marbles
