P(A)=(|A|)/(|\Omega|)


\Omega=\{1;\ 2;\ 3;\ 4;\ 5;\ 6\}\to|\Omega|=6

The first roll:


A_1=\{1;\ 3;\ 5\}\to|A_1|=3\\\\P(A_1)=(3)/(6)=(1)/(2)

The second roll:


A_2=\{1;\ 2\}\to|A_2|=2\\\\P(A_2)=(2)/(6)=(1)/(3)

Probability of the situation:


P(A)=P(A_1)\cdot P(A_2)\\\\P(A)=(1)/(2)\cdot(1)/(3)=(1)/(6)

Answer:
\boxed{(1)/(6)}
