Empat mata uang logam dilantunkan 6 kali. tentukan frekuensi harapan muncul satu angka dan tiga gambar

fh = 4/16 * 6
    = 24/16
    = 3/2 kali

ruang sample :AAAA,AAAG,AAGA,AAGG,AGAA,AGAG,AGGA,AGGG,GAAA,GAAG,GAGA,GAGG,GGAA,GGAG,GGGA,GGGG n(s)= 16
n(a)={(GGAG,GGGA,GAGG,AGGG)} n(a)=4
p(a)= 4/16 =1/4

FH(a) = n.p(a)
         = 6.1/4
         = 6/4
         = 3/2
