b. p= 15/36
maaf kalau salah
semoga membantu:)
muncul jumlah 7 = {(1,6),(2,5),(3,4),(4,3),(5,2),(6,1)} --> n(A) = 6
P(jml7) = 6/36 = 1/6
muncul jmlh < 7
- jml 2 = {(1,1)}
- jml 3 = {(1,2),(2,1)}
- jml 4 = {(1,3),(2,2),(3,1)}
- jml 5 = {(1,4),(2,3),(3,2),(4,1)}
- jml 6 = {(1,5),(2,4),(3,3),(4,2),(5,1)}
n(A) = 15
P(jml <7) = 15/36 = 5/12
