If two people are chosen at random, what is the probability that they were born on different days of the week?

OpenStudy (anonymous):

6/7

OpenStudy (anonymous):

why?

OpenStudy (chihiroasleaf):

is it all the question?

OpenStudy (anonymous):

You choose Joe and Moe. Joe is born on some day, don't care which. The probability that Moe is born on the very same day is 1/7. So the probability that he is NOT is 6/7.

OpenStudy (anonymous):

7/7-1/7?

OpenStudy (anonymous):

the answer booklet says 6/7
