(1-1/2)*(1-1/3)*(1-1/4)*……*(1-1/2013)*(1-1/2014)(1-1/2)*(1-1/3)*(1-1/4)*……*(1-1/2013)*(1-1/2014)(1-1

(1-1/2)*(1-1/3)*(1-1/4)*……*(1-1/2013)*(1-1/2014)
(1-1/2)*(1-1/3)*(1-1/4)*……*(1-1/2013)*(1-1/2014)

(1-1/2)*(1-1/3)*(1-1/4)*……*(1-1/2013)*(1-1/2014)
解
(1-1/2)*(1-1/3)*(1-1/4)*……*(1-1/2013)*(1-1/2014)
=(1/2)(2/3)(3/4)(4/5)……(2012/2013)(2013/2014)
=1×(1/2014)
=1/2014
