You will roll two standard dice together 5 times. You are interested in the outcome where both dice are six. Let X be the number of times you observe this outcome. Answer following questions.

1) What are the possible values for X? (values the random variable X can take)

2) Is X binomial random variable? If so, state its parameter n and p. If not, explain why.

3) Find the probability that you will see both dice being six at least once. Round your answer to the three decimal places.

4) Find mean and variance of X.

Roll a die and let its outcome be the random variable X. Let Y be the random variable of “sum of X many dice rolled”. So, if X is 3, then we roll 3 dice and add the faces together to find Y . (a) Are X and Y independent? Explain. (b) Compute E[Y]

Craps is a dice game in which the players make wagers on the outcome of the roll, or a series of rolls, of a pair of dice. Most outcomes depend on the sum of the up faces of two, fair, six-sided dice. A) Describe the sample space for all possible outcomes of rolling two dice. How many ways are there to roll a 5? b)Determine all possible random variable values and the probability of those outcomes. Find the probability of...

You roll a pair of fair dice 20 times. Each time, the sum of the two dice values is recorded. What is the probability that you will roll an 7 (the sum of the two dice values = 7) at least (5) times? Assuming that each roll of the dice is independent
