| - We roll two physically identical dice. Let’s call event $A$ when we roll a 2 on either or both dice, and event $B$ when we roll a 3 on either or both dice. What is the probability of the event, when after rolling a 3, we immediately roll both a 2 and a 3 at the same time? (Rolling a 3 means that at least one die shows a 3.) // | - We roll two physically identical dice.
