MCQ
Choose the correct answer from the given four options : The probability of getting a bad egg in a lot of $400$ is $0.035.$ The number of bad eggs in the lot is :
  • A
    $7$
  • ✓
    $14$
  • C
    $21$
  • D
    $28$
✓

Answer

Correct option: B.
$14$
Here, total number of eggs $= 400$
Probability of getting a bad egg $= 0.035$
$\Rightarrow\ \ \frac{\text{Number of bad eggs}}{\text{Total number of eggs}}=0.035$
$\Rightarrow\ \ \frac{\text{Number of bad eggs}}{400}=0.035$
$\therefore\ \ \text{Number of bad eggs}=0.035\times400=14$
