It has a probability of 2 out of 36 chances as there are only two ways it can happen out of 36 different combinations that can be rolled. Product means multipication also in Maths
The first probability on the first roll is that Dice 1 must be a 5 and Dice 2 must be a 6 so that 5x6=30
The second probability on the second roll is that Dice 1 must be 6 while Dice 2 must be 5 so that 6x5=30
That is the only two ways out of 36 different combinations that can be made by rolling to Die. Therefore the probability is 2 out of 36
