Options

Solution
The probability of getting a bad egg in a lot of 400 is 0.035. The number of bad eggs in the lot is 14.
Explanation:
Here, Total number of eggs = 400
Probability of getting a bad egg = 0.035
⇒ `"Number of bad eggs"/"Total number of eggs"` = 0.035
⇒ `"Number of bad eggs"/400` = 0.035
∴ Number of bad eggs = 0.035 × 400 = 14
