Birthday of a man is not known what is the probability that he was born on any day except sunday

Please find below the solution to the asked query:

We know formula for probability : Probability P ( E )  = $\frac{\mathrm{Total} \mathrm{number} \mathrm{of} \mathrm{desired} \mathrm{events} \mathrm{n} ( \mathrm{E} )}{\mathrm{Total} \mathrm{number} \mathrm{of} \mathrm{events} \mathrm{n} ( \mathrm{S} )}$

We know : Total number of days  =   7  ( Days in a week )

So,

n ( S ) =  7

And

Days except Sunday =   6 , So

n ( E ) = 6

Therefore,

Probability of man was born on any day except Sunday = $\frac{\mathbf{6}}{\mathbf{7}}$                    ( Ans )
