To tell whether a person is an engineer, or a mathematics/ Operations

type, give them the following problem:

A box contained 50 red socks and 50 green socks. You withdrew two socks;
one
green and one red. What is the probability of having a matching pair on
the
next withdrawal?

The question is too vague to generate a unique correct answer.

On the second draw, do you toss the original two socks and draw another
pair?

Or you do draw one additional sock to add to the current set, from which you
try to make a matched pair?

Pretty much ousted myself with that response...
