Re: Birthday Cake Wouldn't it just be one over twice the number of cuts, i.e., the average size of one piece? The actual sizes and locations of the cuts don't matter. stevo

Re: Birthday Cake Jason, the value can't be 1/4 regardless of n. As an example suppose n=1 so the cake is divided into two (equal) halves. In that case the piece containing the

Re: Birthday Cake So you have a round birthday cake with a candle placed on it. You make n random cuts through the center. The average size of a piece is 1/(2n). n/2 pieces will
