B2 Answer ALL parts (a) — (c). (a) An engineering company is manufacturing integrated circuits (ICs) at an equal rate using five different techniques: A, B, C, D and E. An engineer reports that the probabilities of a defective ICs from each technique is: A - 1%, B-2%, C- 3%, D-3%, and E-4%. An IC is selected at random. Calculate the probability that the IC is defective. Illustrate your answer with a probability tree. (b) Your third-year project supervisor gives you the following probability density function with continuous random variable X to model: f(x) = 0.02(10-x) 0≤x≤ 10 Equation (B6) Sketch a graph of the probability density function defined in Equation (B6). Explain and show how you would check mathematically if Equation (B6) is a valid probability density function. Explain all the steps used in your proof. (c) A civil engineer finds an abandoned building contains on average 2 broken bricks per 800m². Define a probability distribution, P(x) for the number of broken bricks (x) in an area of 400m². Hence calculate the probability of there been more than 4 broken bricks in a 400m² area. Explain any assumptions made in your calculations and answers.

Answer ALL parts (a)-(c).
(a)
An engineering company is manufacturing integrated circuits (ICs) at an equal
rate using five different techniques: A, B, C, D and E. An engineer reports that
the probabilities of a defective ICs from each technique is: A - 1%, B-2%, C-
3%, D-3%, and E-4%. An IC is selected at random. Calculate the probability
that the IC is defective. Illustrate your answer with a probability tree.
(b)
Your third-year project supervisor gives you the following probability density
function with continuous random variable X to model:
f(x) = 0.02(10-x) 0≤x≤ 10
Equation (B6)
Sketch a graph of the probability density function defined in Equation (B6).
Explain and show how you would check mathematically if Equation (B6) is a
valid probability density function. Explain all the steps used in your proof.
(c)
A civil engineer finds an abandoned building contains on average 2 broken
bricks per 800m². Define a probability distribution, P(x) for the number of
broken bricks (x) in an area of 400m². Hence calculate the probability of there
been more than 4 broken bricks in a 400m² area. Explain any assumptions
made in your calculations and answers.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F98a2975c-b075-4e7f-95a3-3742d529c071%2Fe6cd7bde-1ab7-4e2a-ad7f-f05958cc85c9%2Fxadnf6_processed.png&w=3840&q=75)
