(5) A fair 6-sided dice is rolled twice. The fairness of the dice consists of the following facts: (i) no face of the dice is likelier to be rolled than any other (so a roll of a 5 and a roll of a 3 are equiprobable) and (ii) the dice has no “memory” - each roll is independent of any other. 5.1:

What is the probability that you’ve first rolled a 3 and the pair of rolls sums to something more than 4?

5.2: Given that you’ve first rolled a 3, what is the probability of that the pair of rolls sums to something more than 4?

5.3: Given that the sum of the two rolls is either exactly 7 or exactly 6, what is the probability that the first roll is a 2 and the second roll is something greater than 3?

An experiment consists of rolling six-sided dice twice. &

An experiment consists of rolling six-sided dice twice. (10) List the sample space for this experiment. Find the probability distribution for this experiment where x represents the number of even numbers in the 2 rolls. Find the mean of the probability distribution. Find the standard deviation of the probability distribution. Would it be unusual to get 2 even numbers? Why or why not? (show your work)

6 fair 12-sided dice are rolled. (a) [3 marks] Find the conditional probability that at least one die lands on 3 given that all 6 dice land on different numbers. (b) [2 marks] True or False: If X is the maximum of the 6 numbers from one roll, and Y is the minimum of the 6 numbers from one roll, then X and Y are independent random variables.

One red (6 sided) and one white (6 sided) dice is rolled. The random variable X has the value 1 if the red dice shows a number max 2 and is 2 else. The random variable y has the value 1 if the white dice shows a uneven number and is 2 else. A) determine the common probability function (x, y) B) determine the marginal probability functions of x and y C) calculate e(x), e(x^2), var(x), e(y), e(y^2), and var(y)
