ΩA=(1;1),(1;2),(1;3),(1;4),(1;5),(1;6)(2;1),(2;2),(2;3),(2;4),(2;5),(3;1),(3;2),(3;3),(3;4),(4;1),(4;2),(4;3),(5;1),(5;2),(6;1)
ΩA={(1;1),(1;2),(1;3),(1;4),(1;5),(1;6)(2;1),(2;2),(2;3),(2;4),(2;5),(3;1),(3;2),(3;3),(3;4),(4;1),(4;2),(4;3),(5;1),(5;2),(6;1)}
Tập ΩAΩA có 2121 phần tử.
Vậy P(A)=2136=712P(A)=2136=712.
mong hiểu nha
ΩB=(6;1),(6;2),(6;3),(6;4),(6;5),(6;6),(1;6),(2;6),(3;6),(4;6),(5;6)⎫
ΩB={(6;1),(6;2),(6;3),(6;4),(6;5),(6;6),(1;6),(2;6),(3;6),(4;6),(5;6)}
Tập ΩBΩB có 1111 phần tử.
Vậy P(B)=1136P(B)=1136.
ΩC={(6;1),(6;2),(6;3),(6;4),(6;5),(1;6),(2;6),(3;6),(4;6),(5;6)}ΩC={(6;1),(6;2),(6;3),(6;4),(6;5),(1;6),(2;6),(3;6),(4;6),(5;6)}
Vậy ΩCΩC có 1010 phần tử.
Do đó P(C)=1036=518.P(C)=10/36=5/18.
