    Computing in Universe of Discourse

    Let E = {a,b,c,d,e,f} be a universe of discourse. Let A = {a}, B = {b, c, d}, C = {f,a,d}. Compute the following:

    I'd like to know if these answers are correct. Thanks in advance

    A (union) B = {a,b,c,d}

    B (intersection) C = {d}

    B^c = {a,e,f}

    A (triangle) C = {f,d}

    C\A {f,d}

    You can learn to use LaTeX.
    [TEX]A\cup B = \{a,b,c,d\}[/TEX]

    [TEX]B \cap C = \{d\}[/TEX]

    [TEX]B^c = \{a,e,f\}[/TEX]

    [TEX]A \Delta C = \{f,d\}[/TEX]

    [TEX]C\setminus A= \{f,d\}[/TEX]

    GIVES
    A\cup B = \{a,b,c,d\}

    B \cap C = \{d\}

    B^c = \{a,e,f\}

    A \Delta C = \{f,d\}

    C\setminus A= \{f,d\}

    They are correct.
