If one die is greater than 3 and the other 3 or less, the expected value is 5 + 3. that the sum of the two dice is > 3 = 1 - P(sum 9) = 1 − —6 36 = 30 — 36 = 5— 6 ≈ 0. ‘2’ – 1/36 ‘3’ – 2/36 ‘4’ – 3/36 ‘5’- 4/36. Experiment seven. Here is a hint: first compute the probability of getting 2, 3, 4, or 5 of a kind, or all different numbers in the first roll; then try to compute the probability of passing from having i of a kind in a roll to having j on the next roll and try to use these "transition probabilities". This is very simple question to answer so don't be serious. Two examples given in class: 1) If we roll four dice, what is the probability of at least one six? a) Consider the complement problem, there is a 5/6 probability of not rolling a six for any given die, and since the four dice are independent, the probability of not rolling a six is (5/6) 4= 54/6 = 625/1296. It had previously been argued that since. They should point out that >. But in the throw of two dice, the different possibilities for the total of the two dice are not equally probable because there are more ways to get some numbers than others.
