Question
**Problem Statement:** A shipment of 30 computers has arrived at a store. The manufacturer of the computers called the store manager saying that 8 of the computers were defective. If the store has already sold 5 of these computers, what is the probability that at least two is defective? **Solution Attempts:** - Calculation of combinations: - \( ^5C_2 = \frac{5 \times 4}{2 \times 1} = 10 \) - Interpretation of results: - The probability of at least 2 defective computers being sold is calculated using these combinations. - There might have been an error noted with the circled number "−7" and "−3" which could indicate attempts or errors in calculations beyond what is shown. - Intermediate steps might include: - Adjustments or corrections as possibly indicated by the annotations in the image. - Calculations: - It appears there is reference to the number of ways computers can be sold as well as combinations attempted. **Graphical Illustrations or Diagrams:** - No graphs or diagrams are included in the image. However, scratch work and trial calculations are visible to showcase attempted solutions. **Conclusion:** While the transcribed solution is partially visible, the outlined approach addresses combinatorial probability. No specific probability value is confirmed in the visible solution. For educational purposes, learning to apply combination formulas accurately is essential in solving problems involving probability and defective items.
