Questions: Digitalis is a technology company that makes high-end computer processors. Their newest processor, the luteA, is going to be sold directly to the public. The processor is to be sold for 3200, making Digitalis a profit of 384. Unfortunately, there was a manufacturing flaw, and some of these luteA processors are defective and cannot be repaired. On these defective processors, Digitalis is going to give the customer a full refund. Suppose that for each luteA there is a 12% chance that it is defective and an 88% chance that it is not defective.
If Digitalis knows it will sell many of these processors, should it expect to make or lose money from selling them? How much?
To answer, take into account the profit earned on each processor and the expected value of the amount refunded due to the processor being defective. Digitalis can expect to make money from selling these processors. In the long run, they should expect to make dollars on each processor sold. Digitalis can expect to lose money from selling these processors. In the long run, they should expect to lose dollars on each processor sold. Digitalis should expect to neither make nor lose money from selling these processors.
Transcript text: Digitalis is a technology company that makes high-end computer processors. Their newest processor, the luteA, is going to be sold directly to the public. The processor is to be sold for $\$ 3200$, making Digitalis a profit of $\$ 384$. Unfortunately there was a manufacturing flaw, and some of these luteA processors are defective and cannot be repaired. On these defective processors, Digitalis is going to give the customer a full refund. Suppose that for each luteA there is a $12 \%$ chance that it is defective and an $88 \%$ chance that it is not defective.
If Digitalis knows it will sell many of these processors, should it expect to make or lose money from selling them? How much?
To answer, take into account the profit earned on each processor and the expected value of the amount refunded due to the processor being defective.
Digitalis can expect to make money from selling these processors. In the long run, they should expect to make $\square$ dollars on each processor sold.
Digitalis can expect to lose money from selling these processors. In the long run, they should expect to lose $\square$ dollars on each processor sold.
Digitalis should expect to neither make nor lose money from selling these processors.
Solution
Solution Steps
Step 1: Calculate Probabilities
For the luteA processors, the probabilities of being defective and non-defective are given as follows:
Probability of being non-defective: \( P(X = 1) = p = 0.88 \)
Probability of being defective: \( P(X = 0) = 1 - p = 0.12 \)
Step 2: Calculate Mean and Variance
The mean and variance of the Bernoulli distribution can be calculated as:
Mean:
\[
\mu = 1 \cdot p + 0 \cdot (1 - p) = p = 0.88
\]
The expected profit per processor is calculated using the formula:
\[
\text{Expected Profit} = (\text{Profit if non-defective}) \cdot P(\text{non-defective}) - (\text{Refund if defective}) \cdot P(\text{defective})
\]
Substituting the values:
\[
\text{Expected Profit} = 384 \cdot 0.88 - 3200 \cdot 0.12 = 337.92 - 384 = -46.08
\]
Step 4: Determine Financial Outcome
Since the expected profit is negative:
\[
\text{Expected Profit} = -46.08
\]
This indicates that Digitalis should expect to lose money from selling the processors.
Final Answer
Digitalis should expect to lose money from selling the processors, with an expected loss of \\(\boxed{-46.08}\\).
