You are given: (i) Low-hazard risks have an exponential claim size distribution with mean 0. (ii) Medium-hazard risks have an exponential claim size distribution with mean 20 . (iii) High-hazard risks have an exponential claim size distribution with mean 30. (iv) No claims from low-hazard risks are observed. (v) Three claims from medium-hazard risks are observed, of sizes 1, 2 and 3. (vi) One claim from a high-hazard risk is observed, of size 15. Determine the maximum likelihood estimate of 0. (A) 1 (В) 2 (C) (D) 4 (E) 3.

When a sample contains 100 or more cases, what is the correct probability distribution to use?

Find the magnitude of v. V = = (4, 3) v || v|| =
