A 7-point semi quantitative risk analysis produced the following 20 risk values: 10; 42; 1; 36; 5; 2; 7; 28; 14; 2; 4; 2; 6; 1; 3; 1; 5; 24; 1; and 2. Using the Pareto method, determine the critical risks for these risk values. Show the calculations. (6)

8. Determine the risk leverage factor for the following 4 cases and indicate if the control will be financially viable. (4)

Risk No	P-original estimate	Total loss original estimate (R)	P-after control	Total loss after control (R)	Cost of control (R)
A	0,80	9800	0,40	9800	2300
B	0,75	8500	0,75	3100	3500
C	0,55	4800	0,20	4800	2400
D	0,70	9300	0,70	4500	3400
