A/G = AAA/AAG
A : A/G -> A/G = AGA/AGG
. A/G = GAA/GAG
G : A/G- > A/G = GGA/GGG
jadi P(S) "semuanya" = 8
yang 3 gambar P(A) = 1
P(A)/P(S) = 1/8
b)
peluang muncul gambar = 1/2
peluang muncul angka = 1/2
Peluang muncul 2 gambar dari pelemparan tiga keping uang logam:
= 3C2 (1/2)^2 (1/2)^1
= 3!/(2!1!) 1/4 1/2
= 3/8
Peluang muncul 3 gambar dari pelemparan tiga keping uang logam:
= 3C0 (1/2)^3 (1/2)^0
= 3!/(3!) 1/8 1
= 1/8
Peluang muncul sekurang-kurangnya 2 gambar = 3/8+1/8 = 4/8 = 1/2
semoga membantu :)
