SECTION
Attempt any two questions from this section. 2x20=40

1. What do you mean by survival distribution function? Discuss how you would derive future lifetime from survival distribution function.

2. The annual continuously compounded interest rate is given as 0.11. The stock of a company Colra trader trades for Rs 23 per share, and the annual continuously compounded dividend yield on stock is 0.05, in two months, its stock will trade for either Rs 18 per share or Rs 29 per share. The strike price of a European Call option on Colra's stock is Rs 25. Using the one periodbinomial option pricing model, find the price to-day for one such call option of Colra's stock.

3. Name the three distributions to which extreme of a series converges to. Which of these can be used to analyse financial data? Give reasons in support of your answer and discuss the method of estimation of the relevant distributions.

4. Discuss the features of classical Credibility.

If the number of claims has a Poisson distribution, compute the probability of being within of a mean of 100 claims using the Normal Approximation to the Poisson distribution.
