Question

make a tree diagramshowing all outcomes for rolling two dice

Answer 1

A standard die has six sides with numbers 1, 2, 3, 4, 5 and 6. If the die is fair (and we will assume that all of them are), then each of these outcomes are equally likely. Since there are six possible outcomes, the probability of obtaining any side of the die is 1/6. Thus the probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6 and so on for 3, 4, 5 and 6.
