Answer: 26 dollars
Step-by-step explanation:
The owner needs to consider that:
To measure the risk she can multiply the probability of an event to happen (P)* the impact (I) (in this case the impact is the cost).
All these eventes can be considered as independent between each other (no correlation), so you can add their P*I.
In this case:
P1*I1= 1%*550=5.5
P2*I2=6%*150=9
P3*I3=15%*100=15
So, the expected value of what she may spend for repairng is = P1*I1+P2*I2+P3*I3= 5.5+9+15= 29.5
She shoould not spend more than 29.5 dollars, otherwise, she will spend more in the surge supresor than in expected reapring value
