Draw a histogram for the intervals 4-6, 7-9, 10-12, and 13-15 using the following data: 8, 9, 5, 14, 5, 14, 15, 7, 13, 6, 4, 10, 6, 6, 7, 5, 5, 12, 9, 8

Let u = {q, r, s, t, u, v, w, x, y, z} a = {q, s, u, w, y} b = {q, s, y, z} c = {v, w, x, y, z}. list the elements in the set. a ∩ (b ∪ c)a) {q, s, w, y}b) {q, y, z}c) {q, s, u, w, y, z}d) {q, r, w, y, z}
