Question

The probability of getting a rotten egg in a lot of 400 eggs is 0.25 Find the number of rotten eggs in the lot?

Answer 1

Number of possible outcome is 400 eggs
Number of rotten eggs be 'x'
P(E) = x÷400
0•25 =x÷400
X= 0.23×400
X= 100 eggs

Answer 2

Solution :-

Let the number of rotten eggs be x.

Probability = 0.25 (given)

Total outcomes = 400

⠀

⠀ $P(E)= \dfrac{favourable \: outcomes}{total \: outcomes}$

⠀

$0.25 = \dfrac{x}{400} \\ \\ 0.25 \times 400 = x \\ \\ 100 = x \\ \\ x = 100$

Therefore, the number of rotten eggs are 100.
