You are given the following about a portfolio of risks:

• Risks are classified into three classes: 10% belong to class A, 30% belong to class B and 60% belong to class C.
• Losses for each risk are uniformly distributed on an interval [a,b] with a and b dependent on class:

Class	a	b
A	0	1,500
B	500	2,300
C	100	1,000

Determine the expected loss for a randomly selected risk given that the loss is greater than 1,000.
