Answer 1

Answer #1

Answer)

Probability is given by favorable/total

Total = 7

As there are 7 days in a week

Now, first one can have any one from 7 as his or her birth day

So favorable in this case is = 7

But for second one we have favorable = 6 (as it cannot have same birthday )

P(two randomly selected people were born on different days of the week)

= (7/7)*(6/7)

= 0.85714285714
