In a box containing 100 bulbs, 10 are defective. The probability that out of a sample of 5 bulbs, none is defective is(A) 10-1 (B) `(1/2)^5` (C) `(9/(10))^5` (D) `9/(10)`

Explanation

To solve the problem of finding the probability that none of the 5 sampled bulbs is defective, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Total Number of Bulbs and Defective Bulbs**:
- Total bulbs = 100
- Defective bulbs = 10
- Non-defective bulbs = Total bulbs - Defective bulbs = 100 - 10 = 90
