  • 1) n(S) = 2⁴ = 16

    2) n(S) = 6
    n(A) = (1,3,5) = 3
    n(P) = 3/6 = ½

    3) n(S) = 6² = 36
    n(A) = (1,2)(1,4)(1,6)(3,2)(3,4)(3,6)(5,2)(5,4)(5,6) = 9
    n(P) = 9/36 = ¼

    5) n(S) = 6² = 36
    n(A) = (1,5)(2,4)(3,3)(4,2)(5,1) = 5
    n(P) = 5/36

    peluang kelereng merah = 6/21 = 2/7



    6. bilangan prima pada dadu ={2,3,5}
    peluang 3/6 = 1/2
    10kali = 1/2 x jumlah pelemparan
    jumlah pelemparan = 20 kali

    7. peluang = 3/12 = 1/4

    8. peluang = 3/9 = 1/3

    9 . peluang = 3/8
    frekuensi harapan = 3/8 x 80
    FH = 30 kali

    10. peluang turun hujan = 0.6

    peluang tidak turun hujan = 1-0.6
    =0.4
