Suppose Shristi owns a house that is worth $490,000 located in a fire hazard zone. There is a 2% (or 0.02) chance that her house will catch a fire in which case it will be completely destroyed (and 98% or 0.98 chance that it will remain intact). What is the expected value of her house?

Question

Suppose Shristi owns a house that is worth $490,000 located in a fire hazard zone.  There is a 2% (or 0.02) chance that her house will catch a fire in which case it will be completely destroyed (and 98% or 0.98 chance that it will remain intact). What is the expected value of her house?

The problem asks for the expected value of Shristi's house given two possible outcomes and their probabilities.

Step 1: Identify outcomes and probabilities. The house is destroyed with probability 0.02, yielding a value of $0. The house remains intact with probability 0.98, yielding its full value of $490,000.

Step 2: Apply the expected value formula. EV = (probability of outcome 1 × value of outcome 1) + (probability of outcome 2 × value of outcome 2).

Step 3: Compute each term. For destruction: 0.02 × 0 = 0. For intact: 0.98 × 490,000 = 490,000 − (0.02 × 490,000) = 490,000 − 9,800 = 480,200.

Step 4: Sum the terms. EV = 0 + 480,200 = 480,200.

Step 5: Interpret the result. The expected value represents the long-run average value per such house if this risk scenario were repeated many times; on average, each house would contribute $480,200 to the expected value over many trials.

Note: There are no multiple-choice options provided to evaluate here; the calculation follows directly from the two possible outcomes and their probabilities.
