Problem 5 (10 points): A computer system uses passwords that are six characters, and each character is one of the 26 letters (a-z) or 10 integers (0-9). Uppercase letters are not used. Let A denote the event that a password begins with a vowel (either a, e, i, o, or u), and let B denote the event that a password ends with an even number (either 0, 2, 4, 6, or 8). Suppose a hacker selects a password at random. Determine the following probabilities: (a) P(A) (b) P(B) (c) P(A $\cap$ B) (d) P(A $\cup$ B)

Assume that each year a company normally produces and sells 80,000 units of its only product for $40 per unit. The company's average unit costs at this level of activity are given below: Direct materials $ 9.50 Direct labor 10.00 Variable manufacturing overhead 2.80 Fixed manufacturing overhead 5.00 Variable selling expenses 1.70 Fixed selling expenses 4.50 Total cost per unit $ 33.50 The company's relevant range of production is 70,000 - 100,000 units. It has an opportunity to sell 20,000 more units to new overseas customer. The import duties and foreign permits associated with the order would cost $16,000. However, the only selling cost associated with the order would be $1.50 per unit. What is the minimum price that the company could charge on this order and still break even with respect to this opportunity? Multiple Choice $21.60 $23.80 $26.30 $24.80
