tiga buah uang logam dilempar bersamaan Tentukan: a. peluang muncul paling sedikit satu gambar b. paling sedikit satu angka c. ketiganya gambar d. ketiganya ang

a.1(G)=1/2x1/2x1/2=1/8 * 3=3/8
2(G)=1/2*1/2*1/2=1/8*3= 3/8
3(G)=1/2*1/2*1/2=1/8
Peluang=3/8+3/8+1/8=7/8
b. 1/8
c. 1/8

1. kejadian = GAA, AGA, AAG, AGG, GAG, GGA, GGG
N(A)= 7
n(s) = 2^3= 8

p(a) = n(a)/ n(s)
= 7/8

2. kejadiannya = AGG, GAG, GGA, AAG, AGA, GAA, AAA
N(A)= 7
n(s) = 2^3= 8

p(a) = n(a)/ n(s)
= 7/8

3. kejadiannya = GGG
N(A)= 1
n(s) = 2^3= 8

p(a) = n(a)/ n(s)
= 1/8

4. kejadiannya= AAA
N(A)= 1
n(s) = 2^3= 8

p(a) = n(a)/ n(s)
= 1/8


semoga mmbantu
