1. Let U = {r, s, t,u, v, w, x, y,z}, D = {s, t, u,v, w}, E = {v, w,x}, and F = {t, u}. Use rosternotation to list the elements of D ∩ E.
| a. | {v, w} |
| b. | {r, s, t, u, v,w, x, y, z} |
| c. | {s, t, u} |
| d. | {s, t, u, v, w,x, y, z} |
2. Let U = {r, s,t, u, v, w, x,y, z}, D = {s, t,u, v, w}, E = {v,w, x}, and F = {t, u}.Use roster notation to list the elements of D ê“´E.
| a. | {v, w} |
| b. | {r, s, t, u, v,w, x, y, z} |
| c. | {s, t, u} |
| d. | {s, t, u, v, w,x} |
3. Let U = {r, s,t, u, v, w, x,y, z}, D = {s, t,u, v, w}, E = {v,w, x}, and F = {t, u}.Use roster notation to list the elements of E ∩F.
| a. | {t, u, v, w, x} |
| b. | {t, u, v, w, x} |
| c. | {Ø} |
| d. | Ø |
4. Let U = {r, s, t,u, v, w, x, y,z}, D = {s, t, u,v, w}, E = {v, w,x}, and F = {t, u}. Use rosternotation to list the elements of (E ꓴ F)' ∩D.
| a. | Ø |
| b. | {t, u, v, w, x,z} |
| c. | {s} |
| d. | {r, t, u, v, w,x, y, z} |
