A little girl has a 96-pack of crayons. She picks up crayons, at random, to check the color, and she leaves them in a separate pile after inspecting the color. She pulls crayons out of the pack until she gets the sea foam green crayon. a) What is the expected number of crayons she will check until she finds sea foam green? b) Assume instead that she puts each crayon back in the box before randomly drawing the next crayon. Now how many crayons does she expect to check until she finds sea foam green?
