A building contractor requires a roll of roofing felt. There are threesuppliers in the area and the probabilities (based on his previousexperiences and the location of the suppliers) that the contractor willinstruct his vanman to visit a particular supplier are:A: the vanman goes to supplier A, P[A] = 0.6B: the vanman goes to supplier B, P[B] = 0.2C: the vanman goes to supplier C, P[C] = 0.2Each supplier stocks roofing felt produced by two manufacturers, X andY. Both types of roofing felt sell at the same price and both satisfy thecurrent building regulations. The stock situation at each of the suppliersis:SupplierABCNo. of 'X' rolls103030No. of 'Y' rolls302010The vanman will be told by his employer which supplier to visit.Which roll type is the vanman most likely to return with?

I need help with A, B, C. Three friends (A, B, and C) will participate in a round-robin tournament in which each one plays both of the others. Suppose that P(A beats B) = 0.2P(A beats C) = 0.4P(B beats C) = 0.7 and that the outcomes of the three matches are independent of one another. (a) What is the probability that A wins both her matches and that B beats C? and What is the probability that A wins both her matches? (b) What is the probability that A loses both her matches? (c) What is the probability that each person wins one match? (Hint: There are two different ways for this to happen.)
Suppose we know that the probabilities P(A) = .5, P(B|A) = .3 and P(A or B) =.3. What is the value for P(A and B)? What is the value for P(B)?
. An electronic assembly consists of two subsystems A and B. The following probabilities are known. P(A fails) = 0.25, P( A and B fail) = 0.14 and P(B fails alone) = 0.15. Evaluate P (A fails alone) P (A fails given that B has failed) (Explain the solution using Venn diagram)
Suppose that Trendy Inc. products a style of a seasonal business suit, Sit-T-Slicker, which has a cost of $500 per unit. The demand during the season for Sit-T-Slicker is generally unknown and could be either: 200, 500, 800, 1100, and 1500 units with equal probabilities. Trendy sells the Sit-T-Slicker suit for $900 per unit during its three-month season, and for $300 per unit when sold after that time. Given the above data, what is the optimal order quantity for the Sit-T-Slicker? What is expected profit? Suppose the probabilities in part a change to 0.05, 0.25, 0.40, 0.25, 0.05 for demand levels 200, 500, 800, 1100, 1500, respectively. What is the optimal order quantity and expected profit in this case? How would better information regarding the demand for the Sit-T-Slicker suit change the data provided in this problem? How would this information affect the answers to part a? Explain.

When a woman goes for shopping she may buy several goods between them clothes and shoes. She has calculated the probabilities of her preferences as follows: The probability that she buys clothes, equals 0.60.6. The probability that she buys shoes and she does not buy clothes, equals 0.20.2. The probability that she buys both clothes and shoes, equals 0.20.2. Find the probability that in one shopping day she: (a) buys at least one of the goods “clothes” or “shoes”. (b) buys clothes and not shoes. (c) buys exactly one of the goods “clothes” and “shoes”. (d) buys at most one of the goods “clothes” and “shoes”.
On Mr. Casper's debate team at Thunderbird High School, 20% of the members are Sophomores, 35% are Juniors and 45% are Seniors. A team member is selected randomly to give the closing argument for the team. If a sophomore gives the closing argument, the team has a probability of 0.25 of winning the debate. If a junior gives the closing argument, the probability of winning is 0.6. If a senior closes, the probability of winning is 0.85. (a) Find the probability that the team wins the debate. b sketch a tree diagram to model this process
Students in a class like to secretly use online calculators in their quizzes. There are three such online calculators favoured amongst the students: WolframAlpha (WA), Symbolab (S), and GeoGebra (GG). A student's favourite calculator changes from quiz to quiz according to the following rules: If a student likes WA best, then it is has a 50% chance of remaining their favourite for the next quiz; 25% of becoming S for the next quiz; and 25% of becoming GG for the next quiz. If a student likes S best, then it has a 50% chance of becoming WA for the next quiz, and a 50% chance of becoming GG for the next quiz. If a student likes GG best, then it has a 33.3% chance of becoming any of the three calculators for the next quiz. For the first quiz, there are 120 who count WA as their favourite; 80 who count S as their favourite; and 50 who count GG as their favourite. What is true about the fourth quiz? Choose one of the following: 1. 115 students favour WA; 52 students favour S; and 83…
