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.

Question

What is the expected value for the number of defective LCDs?

Answer 1

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.
