A fair die is rolled 13 times what is the expected sum of the 13 rolls

P (the sum is 1 when two fair dice are rolled) = 0 / 36 = 0. b] probability that the sum is 4. The outcome that gives the sum as 4 = {(1, 3), (2, 2), (3, 1)} = 3 outcomes. P (the sum is 4 when two fair dice are rolled) = 3 / 36 = 1 / 12. c] probability that the sum is less than the number 13. All the outcomes in the sample space give the sum.

A 6-sided die is rolled three times. (a) Construct the probability distribution table for the number of times the die will land on 6. (b) Determine the expected number of times the die should land on 6. You suspect that a 6-sided die is weighted to reduce the chance of rolling a 6. You perform an experiment where the die is rolled 50 times and. The probability of rolling the same value on each die - while the chance of getting a particular value on a single die is p, we only need to multiply this probability by itself as many times as the number of dice. In other words, the probability P equals p to the power n, or P = pⁿ = (1/s)ⁿ.

Then by linearity of expectation the expected value of n six-sided dice is n ⋅ 7 / 2. The sum Y is given by Y = X 1 + X 2 + ⋯ + X n, where X i is the number rolled on the i th toss. We have E ( X i) = 21 6. Since the expectation of a sum is the sum of the expectations, E ( Y) = 21 n 6. The problem can be easily solved by using the concept.
