me and my friend at work have been having a debate .
there is a man and women at work that everyone suspects is having an affair.
one day out of the blue
they both phoned in sick on the same day , my friend said ,what are the odds of that happening ,
i started to wonder........
i said well if there are 240 working days in a year , and they both have exactly 1 day off a year
it would be 240 * 240 =57600 .. .. so 1 in 57,600
but if they both had exactly 3 days off a year it would be
240 / 3 = 80 ... 80 * 80 = 1 in 6,400
i know there are other things to consider like , we dont know exactly how many
days they both have off a year
but if the cases are as above ,the math is correct i think ?
