The expected value for the number of defective LCDs can be calculated using the formula:
Expected Value (E) = n * p
Where:
- n is the number of LCDs sampled (in this case, 5)
- p is the probability of sampling a defective LCD (in this case, 0.1)
Using the formula, we can calculate the expected value:
E = 5 * 0.1
E = 0.5
Therefore, the expected value for the number of defective LCDs is 0.5.
A manufacturer of liquid crystal displays (LCDs) is studying their production lines. The probability of sampling a defective LCD is 0.1. A sample of 5 LCDs is taken. You may assume that an LCD being defective is independent of any of the others being defective.
