Answer:

Step-by-step explanation:

We would need to multiply the number of trials (which is 500) by the probability of choosing a red in 1 try from the information given.

<em>There are 50 in total, and 8 of them are red, so:</em>

P(red) = $\frac{8}{50}=0.16$

<em>Now we multiply this with 500 to get:</em>

$500*0.16=80$

The correct answer is A.
