Question

the probability of getting rotten egg in a lot of 400 is 0.035 . the number of rotten egg in a lot is a. 1/5 b. 13/50 c. 6/25. d. 1/4​

Answer 1

Let the number of bad eggs = x

Given: Probability of bad eggs = 0.035

Total number of eggs = 400

Probability =

$\frac{number \: of \: favourable \: outcomes}{total \: number \: of \: outcomes}$

$0.035= \frac{x}{400} \\ \\ x = 0.035 \times 400 \\ x = 14$

Total number of rotten eggs = 14

Answer 2

> Let the number of rotten eggs be x .

> Probability of rotten eggs = 0.035 .

> Total number of eggs =

$number \: of \: favorable \: outcomes \div total \: number \: of \: </strong><strong>outcomes[</strong><strong>/</strong><strong>t</strong><strong>ex]</strong></p><p></p><p></p><p><strong>[tex]0.035 = \frac{x}{400}$

$x = 0.035 \times 400$

$x = 14$

Hence, there are 14 rotten eggs.

option D will be the answer.
