Question

The probability of getting a bad egg in a lot of $400$ is $0.035$. The number of bad eggs in the lot is___

Answer 1

Given:

Total number of eggs $=400$

The probability of getting a bad egg $P\left(E\right)=0.035$

Let the number of bad eggs $=x$

We know that,

Probability of getting a bad egg,

$P\left(E\right)=\frac{\text{Number of bad eggs}}{\text{Total number of eggs}}$

$\Rightarrow 0.035=\frac{x}{400}$

$\Rightarrow \frac{35}{1000}=\frac{x}{400}$

$\Rightarrow \frac{35}{1000}\times 400=x$

$\Rightarrow \frac{140}{10}=x$

$\Rightarrow 14=x$

Therefore, the number of bad eggs $=14$
