You have a pair of 4-sided dice. The four sides of each die are numbered 1, 2. 3, and 4. Each time the pair of dice is rolled, you add the numbers from each die. Out of all the possible ways the dice can land, how many of them give you a sum of 5? Number How many ways give you a sum of 8? Number What is the probability of rolling a sum of 7 with these dice? Number

1. Suppose a fair six-sided die is tossed, with N being the resulting number on the uppermost face. Given N, a fair coin is tossed independently until N heads are recorded. Let X be the total number of tails recorded. a. What is the pmf of N? (5 pts) b. Given N = 3, what is the distribution of X? (10 pts) c. What is Pr(X = 1)? (10 pts) d. What is E(X)? (10 pts)

Q3: TRUE OR FALSE You roll three fair dice -- one with seven sides (numbered 1 to 7), one with eight sides (numbered 1 to 8), and one with nine sides (numbered 1 to 9). X = number of dice showing odd numbers facing up. i)There are a fixed number of trials, n. 2)Each trial can be categorized as being either a success or a failure (two outcomes), and X counts the number of successes. 3)The probability of success p...

Please write in detail neatly. Kindly don't use any symbols and shortcut words. Please write the formula appropriately. The question is: Consider an unbiased 4-sided die where the sides are numbered 1, 2, 3, 4, and a biased coin with probability of head P(H) =4 divided by 7. A chance experiment consists of rolling the die once and then tossing the coins many times as the number showing on the die. Let X represent the outcome of the roll of...
