Go up one level in this thread




our local sunday paper has a regular column with write in problems.
this column is by marylin von sant(spelling?). supposedly she has the highest
female iq in the world. i remember this problem was in her column.
her answer was once any door is opened, and only two doors are left,
the original odds of 33% are still there, even though there are only two doors
to choose from. i agree with you, it also seems to me that the odds change to
50% once there are only two doors left.

we have an engineer at work that has a PHD. so this is the problem i posed to
him with a twist. this engineer also agrees with marylin. so i asked him once
the first door is open, then lets stop the original story, and add this to it.
now we bring in someone else, now he chooses. what are the odds for the second
person that is choosing. the doctors answer was 50/50 for the second person, but
he said it was still 33% for the original person that chose when there was three
doors.
