A pair of dice are rolled find the following, a) the probability of doubles, b) the odds in favor of a sum greater than 2, c) the probability of sum that is even and less than 5

Answer 1

Again, either-or probabilities are found by adding the individual probabilities. Each combination of the die has a 1/36 probability.

a) What are the possible number of doubles? Follow the rule above.

b) This is the same as 1-probability of getting 2 or less with two die.

c) How many ways can you get 2 or 4? Divide that by 36.
