Question

if the probability of drawing a red card from a box is 3/8, what are the odds against drawing a red card from the box

Answer 1

We will write out the ratio for the odds of picking a red card from the box to not picking a red card from the box.

Odds: (5/8)/(3/8) = (5/8)*(8/3) = 5/3 or 5:3

Your odds of not picking a red card from the box is 5 to 3.
