Question 926588
Here's my guess:
In each row, there are {{{ 24 }}} different pairs of seats
In {{{ 10 }}} rows, that make {{{ 240 }}} ways that they
can sit next to each other
------------------------
The total number of different ways that {{{ 2 }}} people
can be seated is:
{{{ 250*249 = 62250 }}}
----------------------
The probability they will sit next to each other is:
{{{ 240/62250 = .003855 }}}
Hope I got it
