Problem 3You're a structural engineer working for a large construction firm. You purchase structuralbeams from three different suppliers: 20% from supplier A1, 20% from supplier A2, and 60%from supplier A3. Based on historical evidence, 10% of the beams from A1 are not directlyusable in commercial construction, same with 12% of beams from A2 and 4% from A3. What isthe probability that a particular beam will not be directly usable in commercial construction?

Three suppliers of structural beams : P(A1) = 20% = 0.20 P(A2) = 20% = 0.20 P(A3) = 60% = 0.60 Beams…

QUESTION 3It has been established that soccer ace Fernandes chances of scoring a penalty is 70 percent all thetime. However, he is a streak shooter, and if he scores on one shot, his probability of scoring it on thepenalty shot immediately following is 0.85. But it has also been pointed out that another soccer starZlatan chances of scoring a goal in any game is 65 percent all the time. However, since he is a streakstriker, and if he scores in one game, his probability of scoring in the game immediately following is0.75.3.1.Write this in the probability notation. 3.2.Calculate the probability that Fernandes will score the penalties on two consecutive shots. 3.3.Calculate the probability that Fernandes scores a penalty because Zlatan has scored twice. 3.4.Are probabilities that Zlatan scores in second game and that he scores in the third gameindependent in this question? Explain.
Johnson Chemicals is considering two options for its supplier portfolio. Option 1 uses two local suppliers. Each has a "unique-event" risk of 4.5%, and the probability of a "super-event" that would disable both at the same time is estimated to be 1.3%. Option 2 uses two suppliers located in different countries. Each has a "unique-event" risk of 14%, and the probability of a "super-event" that would disable both at the same time is estimated to be 0.18%. a) The probability that both suppliers will be disrupted using option 1 is ____ (round your response to five decimal places). b) The probability that both suppliers will be disrupted using option 2 is _____ (round your response to five decimal places).

section 5.5 A personnel director has two lists of applicants for jobs. List 1 contains names of 24 women and 8 men, whereas List 2 contains the names of 9 women and 16 men. A name is randomly selected from List 1 and added to List 2. A name is then randomly selected from the augmented List 2. Given that the name selected is that of a man, what is the probability that a woman's name was originally selected from List 1? Round your answer to four decimal places, if necessary.
