Wilbur went to a dating club one Saturday evening to pick up a date for dinner.
As he entered The Quick Date Club, he saw what he wanted: a tall brunette with a shapely figure. She had the name Alice displayed on a badge dangling from a well-filled blouse.
The system at the The Quick Date Club was to seat an equal number of men and women at random in a row with eight numbered chairs, the numbers and names to be displayed on a screen on the wall.
The rule was that any female sitting next to a male would be eligible for a date request, unmatched persons to be recycled for the next round.
What would you say was the probability that Wilbur sat next to Alice so he could invite her for dinner?
