Question 3 Flaws occur in mylar material is Poisson distribution with a mean of 0.02 flaw per square yard. Calculate the following probabilities. (a) No flaw is found in a square yard of mylar material. (2 marks) (a) At least four flaws are found in twenty square yards of mylar material. (4 marks) (c) Two flaws are found in the first ten square yard of mylar material and five flaws are found in the next ten square yard of mylar material. (4 marks) (TOTAL: 10 marks)

The mean number of flaws per square meter in a length of fabric is 4. Assume that the flaws occur randomly and independently so that the Poisson distribution applies. Answer the following questions to 3 places after the decimal point. a) What is the probability of 2 flaws in a square meter? b) What is the probability of at least 1 flaw in a square meter? c) What is the probability of at most 1 flaw in 2 square meters of fabric?

Q 1: Flaws in a certain type of drapery material appear on the average of two in 250 square feet. If we assume the Poisson distribution, find the probability of i) At least three flaws in 225 square feet ii) At most two flaws in 150 square feet iii) Four flaws in 100 square feet Q 2: Let X and Y have joint probability density function f(x, y) = 4xy, 0 < x < 1, 0 < y < 1 i) Find f(x) ii) Find f(y) iii) Are X and Y are independent random variables?

2. Flaws on a certain tye of drapery material appear on the average of one in 150 square feet. Assume flaws appear according to a Poisson distribution. (a) Find the probability of at most one flaw appearing in 225 square feet of drapery. (b) Find the probability that no flaws appear in 75 square feet of drapery.
