4. Each of the 6 tubes of a radio set has a life length (in yrs) which may be considered as a RV that follows a weibull distribution with parameters α = 25 and β = 2. If these tubes function independently of one another, what is the probability that no tube will have to be replaced during the first 2 months of service? (Refer C: page no : 2.82)

5.It is known that the probability of an item produced by a certain

machine will be defective is 0.05. If the produced items are sent to the market in packets of 20, fine the no. of packets containing at least, exactly and atmost 2 defective items in a consignment of 1000 packets using (i) Binomial distribution (ii) Poisson approximation to binomial distribution. (Refer C: page no : 2.28)
