An assortment of 24 super pumpkin seeds contains 6 that are non-viable. Alice randomly selects 6 of these seeds (without replacement) to plant for the pumpkin growing contest. Some of her selected seeds may be non-viable. Let X = the number of the selected seeds which are non-viable. Need help with f,g,and h.
