Define the sets A, B, C, D, and E as follows: A = {x € R: x < -2} B = {x € R: x > 2} C = {x € R: |x| < 2} D = {x € R: |x| < 2} E = {x € R: x< -2} Use the definitions for A, B, C, D, and E to answer the question. Do the sets B, D, and E form a partition of R? If not, which condition of a partition is not satisfied? No. BUDUE + R. No. DNE + Ø because -2 € D N E. No. B n D + Ø because 2 EDNE. Yes. B n D = Ø, DNE = Ø, and E n B = Ø.
