    E None of these Correct Answer Incorrect Answer

    Solution

    P(E) = ┬а(тБ┤CтВБ + тБ┤CтВБ + тБ┤CтВБ)/(тБ╡┬▓CтВБ) ┬а= (4+4+4)/52 = 12/52 = 3/13 Simplified Solution: Total Cards = 52 Number of kings in a deck = 4; P(getting a King) = 4/52 = 1/13 Similarly, P(getting a Queen) = 1/13 P (getting a Jack) =1/13 P (King or Queen or Jack) = 1/13 + 1/13 + 1/13 = 3/13
