No, it should be a fraction. \(\sf\large Probability ~of~ picking~ a ~red~ marble = \frac{Number~of~Red~marbles}{Number~of~total~marbles}\)

ok we have that as: \(\sf\Large \frac{8}{50}\) Multiply that by 500

8/50 is the probability of getting 1 red marble. So to find out for 500 marbles, we have to multiply by 500.
