Can you elaborate further on this question as this is an assignment topic and you have solved it for some one else.I have pasted the question and the link where you have answered the question.

1- A chartered accountant applies for a job in two firms X and Y. He estimates that the probability of his being selected in firm X is 0.7 and beig rejected in Y is 0.5 and the probability that atleast one of his applications rejected is 0.6. What is the probability that he will be selected in one of the firms?

2-In a factory turning out razor blade, there is a small chance of 1/500 for any blade to be defective. The blades are supplied in a packet of 10. Use Poisson distribution to calculate the approximate number of packets containing blades with no defective, one defective, two defectives and three defectives blades in a consignment of 10,000 packets.

Appreciate your help.

I'd be happy to elaborate on these questions and answers. Can you be a little more specific? For instance, is there a part of the answer that you don't understand or for which you would like more background. I recommend that you look at a good probability and statistics book or website to at least have access to the axioms and the associated algebra. I could then run through it with you.
