JNU SSS 2010 Question 49: Random variables and standard distributions

There are two egg delivery boys you can order eggs from. The probability of the first boy falling and breaking all the eggs is 12\frac{1}{2}21​ and the probability of the second boy falling and breaking all the eggs is 15\frac{1}{5}51​. How would you distribute your order for eggs so as to minimize expected total loss of eggs?

Plain-text version

There are two egg delivery boys you can order eggs from. The probability of the first boy falling and breaking all the eggs is 1/2 and the probability of the second boy falling and breaking all the eggs is 1/5. How would you distribute your order for eggs so as to minimize expected total loss of eggs? (A) Order all your eggs from the first boy (B) Order all your eggs from the second boy (C) Distribute the order for eggs between the two boys equally (D) Order three-fourths of your eggs from the first boy and the rest from the second boy
