Answer:

[tex]0.76[/tex]

Step-by-step explanation:

Probability = Number of favorable outcomes / Number of possible outcomes

There are [tex]16[/tex] favorable outcomes (the [tex]8+8=16[/tex] marables that are either blue or red).

There are [tex]21[/tex] possible outcomes (the [tex]8+5+8=21[/tex] total marables).

P (draw a blue or red marable) [tex]= \frac{16}{21}[/tex] ≈ [tex]0.76[/tex]
