%0 Journal Article %T A Nonmeasurable Set from Coin Flips %A Alexander E. Holroyd %A Terry Soo %J Mathematics %D 2006 %I arXiv %X In this note we give an example of a nonmeasurable set in the probability space for an infinite sequence of coin flips. The example arises naturally from the notion of an equivariant function, and serves as a pedagogical illustration of the need for measure theory. %U http://arxiv.org/abs/math/0610705v2
