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]
