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
b. 14
c. 21
d. 28

Solution:

It is given that

Total number of eggs = 400

Probability of getting a bad egg P(E) = 0.035

Consider x as the number of bad eggs

The formula to find the probability is

P(E) = Number of bad eggs/ Total number of eggs

Substituting the values

0.035 = x/400

By further calculation

35/1000 = x/400

x = 35/1000 x 400

x = 140/10

x = 14

Therefore, the number of bad eggs in the lot is 14.
