    Step-by-step explanation:

    Let S be the sample space

    S={HH, HT, TH, TT}

    n(S)= 4

    A: both the coins with some place

    B: both the coins with different place

    C:at least one tail

    D:at the most one head

    1) A={TT,HH}

    n(A)=2

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

    = 2/4

    = 1/2

    2) B ={HT, TH}

    n(B) = 2

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

    = 2/4

    = 1/2

    3) C= {HT, TH, TT}

    n(C)=3

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

    = 3/4

    4). D={HT, TH}

    n(D) = 2

    P(D) = n(D)/n(S)

    = 2/4

    =1/2
