question in risk management knowledge area

There is a probability of 0.1 that a given risk event will occur in a project. If it occurs it will result in a loss of $10,000. The insurance cost for this event is $700 plus a deductible amount of $250. Should a project manager buy this insurance?

The answer is given as "Yes, since $1000 > $950"

Can someone explain the reasoning please?

 

The solution lies in the question

If the risk occurs the loss of cost will be 10000*0.1=1000

where as the insurance cost is 700 plus 250=950

The insurance cost  (950) is less than 1000.

Thank You for the response
