    Answer:

    (B n C) = {b,c}

    A = {a,b,c}

    B= {b,c,d}

    C= {b,c,e}

    A u (B n C) = {a,b,c}

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

    (A u B) n C = {b,c}

    (A u C) = {a,b,c,e}

    (A u B) n (A u C) = {a,b,c}

    a. A U (B n C)
    B n C = {b,c}
    A = {a,b,c}
    A U (B n C) = {a,b,c} U {b,c} = {a,b,c}

    b. A U B = {a,b,c} U {b,c,d} = {a,b,c,d}

    c. (A U B) n (A U C)

    A U B= {a,b,c,d}
    A U C= {a,b,c,e}

    (A U B) n ( A U C)

    ➡️ {a,b,c,d} n {a,b,c,e}

    ➡️ {a,b,c}
