    Answer:

    a) 1/4

    b) 1/6

    c) 1/12

    Step-by-step explanation:

    Let S be the sample space.

    S={H1,H2,H3,H4,H5,H6,T1,T2,T3,T4,T5,T6}

    n(s) =12

    Events

    A: coin with head and die with prime number .

    B:coin with head and die with composite number.

    C:coin with tail and die with even prime number.

    a) A={H2,H3,H5}

    n(A) = 3

    P(A) =n(A)/n(S)

    =3/12

    = 1/4

    b) B={H4,H6}

    n(B)= 2

    P(B) = n(B)/n(S)

    = 2/12

    = 1/6

    c) C ={T2}

    n(C) = 1

    P(C) = n(C)/n(S)

    = 1/12
