Lapatulllka [165]

Step-by-step explanation:

Number of red = 2
Number of blue = 5
Number of green = 3

total number of marbles = 10

<h3>probability of not choosing a red marble = 1--choosing a red marble.</h3>

Because probability is always one(1).

Probability =

 $1 - \frac{2}{10}$ 

 $\frac{8}{10}$ 

 $\frac{4}{5}$ 

Is the probability of not choosing a red marble.
