Suppose you pay $0.40 to roll a fair 10-sided die with the understanding that you will get $1.10 back for rolling a 1. Otherwise, you get no money back. What is your expected value of gain or loss? Round your answer to the nearest cent (i.e. 2 places after the decimal point), if necessary. Do NOT type a "$" in the answer box.

5. Suppose the six-sided die you are using for this problem is not fair. It is biased so that rolling a 6 is three times more likely than any other roll. For this problem, the experiment is rolling a six-sided die twice. (A): What is the probability that one or both rolls are even numbers (2, 4 or 6’s)? (B): What is the probability that at least one of the rolls is an even number or that the sum of...

You roll a fair 6-sided die once and observe the result which is shown by the random variable X. At this point, you can stop and win X dollars. Or, you can also choose to discard the X dollars you win in the first roll, and roll the die for a second time to observe the value Y. In this case, you will win Y dollars. Let W be the number of dollars that you win in this game. a)...
