Continue Problem 3. Instead of buying one share of each of the four stocks, we want to buy four shares of stock 1. Again,
(i) Find the mean and variance of the value of my stocks one year from now.
(ii) What is the probability that one year from now my total stock value is higher than $104?
Same as Problem 3, please answer the above 2 sub-questions using CFRN and rand(): (a) (10 points) Use CFRN to generate 20 random numbers for X1 and then answer the above 2 sub-questions. (b) (5 points) Use the function rand() in Excel to generate X1. And increase the number of simulation runs from 20 to 200
