Hey guys - got this question at work - would appreciate your help as my probability knowledge is a little rusty..

Basket with 5 balls - 3 black, 2 white... if you draw a black ball you have to pay 1 dollar, if you draw a white ball, you get a dollar... once a ball is drawn, it is not replaced, and you can stop drawing at ANY TIME.

What is the value to playing this game? My back of the envelope is coming to be about 17.5 cents - is that correct?

Thanks in advance and my apologies if this is not the right forum.
