    (1/2) * (1/6) = 1/12

    P(head & 3) = (1/2)(1/6) = 1/12 answer//

    Wow .. someone really doesn't inderstand how to work out a probibility.

    All those thumbs down !

    A coin has two sides .. so the probability of getting a head is 1 in 2

    A coin has six sides .. so the probability of getting a three is 1 in 6

    So .. the probability of of getting both is 1 in 12 ..... (1x1=1 ... 2x6=12)

    What is important that NO ONE is telling you is that a flipping a coin and rolling a die are INDEPENDENT EVENTS. So the Law of Multiplication for Independent Events is: P( A and B) = P(A) * P(B), where A is the first event and B is the second event.

    :-

    P ( head and three) = (1/2) (1/6) = 1/12

    P = 1/2 * 1/6 = 1/12

    P (Head) = 1/2

    P (3) = 1/6

    P (Head) AND P (3) = P (Head) • P (3)

    .................................= 1/2 • 1/6

    .................................= 1/12.....................ANS

    1/6 X 1/2 = .0833%

    The probability of heads is 1/2

    The probability of rolling three is 1/6

    1/2 * 1/6

    = 1/12
