izharulhaq78 $\displaystyle A=\{A\};n(A)=1\\B=\{3,5\};n(B)=2\\S_A=\{A,G\};n(S_A)=2\\S_{B}=\{1,2,3,4,5,6\};n(S_B)=6\\\\P(A\cap B)=P(A)\times P(B)\\P(A\cap B)=\frac{n(A)}{n(S_A)}\times\frac{n(B)}{n(S_B)}\\P(A\cap B)=\frac{1}{2}\times\frac{2}{6}\\\boxed{\boxed{P(A\cap B)=\frac{1}{6}}}$

MicoArrafi Karena ada kata 'dan', maka dinamakan "peluang saling bebas".

A = { A }
n(A) = 1
n(S(A)) = 2
B = { 3, 5 }
n(B) = 2
n(S(B)) = 6

$$\begin{align} P(A\cap B)&=P(A)\times P(B)\\&=\frac{1}{2}\times\frac{2}{6}\\&=\frac{1}{6} \end$
