Vier has a box full of colorful candies. there were 50 pieces of those candies: 20 red, 10 green, 12 yellow and 8 blue. after shaking the box, he randomly selected 2 candies from the box (without replacement). what's the combined probability that the first one was blue and the second one was yellow

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
