The probability for the coins, I would think the answer is 2. They could either be different sides or the same. With the cube there is a probability of 6. there are 6 sides it could land on, and since it is just one cube, it is only 6. Hope this helps!
I did these about 1 year ago but i think you subtract the 6 from 30 and then divide by 4, and that gives u 24/4 which is 6. i barely barely remember some so
