Probility is $1/12 or 8.33(2dp)%$

Explanation:

Possible outcome on first coin is $2$
favourable outcome on a first coin is $1$
So probability is $1/2$

Possible outcome on number cube is $6$
favourable outcome on number cube is $2$
So probability is $2/6=1/3$

Possible outcome on second coin is $2$
favourable outcome on second coin is $1$
So probability is $1/2$

So Probility is $1/2*1/3*1/2=1/12 or 8.33(2dp)%$ [Ans]
