If an integer x is to be selected at random from 1 to 100, inclusive, what is probability x(x+1) will be divisible by 2?	Choose the correct option
A) 3
B) 1
C) 2
D) 4
E) 5
because x(x+1) is always an even product of even*odd or odd*even factors,   there is a probability of 1 that that it will be divisible by 2,   1*1=
