The probability that none of the five have type B* blood is 0.498. (Round to three decimal places as needed.) (c) Find the probability that at least one of the five has type B* blood. The probability that at least one of the five has type B* blood is 0.502. (Round to three decimal places as needed.) (d) Which of the events can be considered unusual? Explain. Select all that apply. O A. The event in part (a) is unusual because its probability is less than or equal to 0.05. B. The event in part (c) is unusual because its probability is less than or equal to 0.05. O C. The event in part (b) is unusual because its probability is less than or equal to 0.05. O D. None of these events are unusual.

A jar contains 12 coins: 6 pennies, 2 nickels and 4 dimes. A child selects 2 coins at random without replacement from the jar. Let X be the sum of the value of the 2 coins. Determine the probability distribution of X. Please enter the values for x in increasing order. Round your answers to three decimal places, if necessary. Hint: If you are picking two different coins, remember that you can pick one first, then the other or the other way around, and you will still end up with the same two coins. X P(X = x) 2 0.015 If you were to randomly draw two coins from this jar, how many cents do you expect to have on average? (Averages of discrete things CAN be decimals!)
