Open in App

Solution

Given,

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

Total married workers = 91

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

P(married) + P(not married) = 1

Here, P(married) = $\frac{91}{364} = 0.25$

So, 0.25 + P(not married) = 1

P(not married) = 1 – 0.25 = 0.75
