Answer:
5/8
Step-by-step explanation:
To find the combined probability we will write as a fraction with the number of occurrences for the specified conditions.
Here, we have 16 marbles total (as 6 + 6 + 4 = 16) and we want to find the probabiliy of choosing either a red or blue marble out of the 16. There are 10 marbles that are either red or blue (as 16 - 6 = 10) so the fraction would be 10/16. However, we still need to get this simplest form.
[tex]\frac{10}{16} = \frac{5}{8}[/tex]
As we cannot simplify 5/8 any further, this is the final answer.
