Question

In a factory of 364 workers, 91 are married. Find the probability of selecting a worker who is not married.​

Answer 1

Answer:

Given,

Total workers (i.e. Sample space) = S = 364

Total married workers = P(married) = 91

Now, total workers who are not married = (E) = 364 – 91 = 273

Method 1: So, P(not married) = E/S = 273/364 = 0.75

Method 2: P(married) + P(not married) = 1

Here, P(not married) = 91/364 = 0.25

So, 0.25 + P(not married) = 1 – 0.25 = 0.75
