**Expected Value Calculation for an Insurance Policy**

**Problem Statement:**
Based on historical data, an insurance company estimates that a particular customer has a 2.7% likelihood of having an accident in the next year, with the average insurance payout being $1900.

If the company charges this customer an annual premium of $200, what is the company's expected value of this insurance policy?

**Explanation:**
The expected value (EV) of an insurance policy from the company's perspective can be calculated considering both the premium received and the potential payout in case of an accident.

**Step-by-Step Calculation:**

1. **Identify Probabilities and Payouts:**
    - Probability of an accident (P_accident): 2.7% or 0.027
    - Probability of no accident (P_no_accident): 1 - P_accident = 1 - 0.027 = 0.973
    - Average insurance payout if an accident occurs: $1900
    - Annual premium paid by the customer: $200

2. **Calculate Expected Payoff from Accidents:**
    - If an accident happens, the company pays $1900.
    - Expected payout due to an accident: P_accident * payout = 0.027 * $1900 = $51.30

3. **Calculate Expected Premiums Collected:**
    - Premium is collected regardless of whether an accident occurs.
    - Expected premium collected: P_accident * $200 + P_no_accident * $200 = $200

4. **Calculate Expected Value (EV):**
    - The company's expected profit/loss from the policy can be calculated as follows:
        EV = Expected Premiums - Expected Payouts
        EV = $200 - $51.30
        EV = $148.70

**Conclusion:**
The company's expected value of this insurance policy is $148.70. This means, on average, the company expects to make a profit of $148.70 per year per customer from this type of policy.
