    Answer: c. R OR E

    e. R′

    f. E

    Step-by-step explanation:

    Outcomes for Red card ={1,2,3,4,5,6} = 6

    Outcomes of Blue card = {1,2,3} =3

    R = event of drawing a red card, B = event of drawing a blue card, E=event of drawing an even numbered card, and O = event of drawing an odd card.

    Then, R= {1R,2R,3R,4R,5R,6R} , B= {1B,2B,3B}

    E={2R, 4R, 6R , 2B}

    O = {1R, 3R, 5R, 3B}

    R or O = { 1R,2R,3R,4R,5R,6R ,3B}   [all elements of R and O]

    B and O = {3B}             [all elements common in B and O]

    R or E = {1R,2R,3R,4R,5R,6R,2B }

    R and O = {1R, 3R, 5R}  [all elements common in R and O]

    R’ = B= {1B,2B,3B}     [all elements except R]

    Blue 2 = 2B belongs to B, R or E, R’ and E.

    Correct options are c. e. f.
