Hey considering an Hash function f(x), that distribute evenly, 1/m, for array size m.
Why the probability of two element when x1!=x2, to collide meaning f(x1)=f(x2) is 1/m and not 1/m^2 ?
my calculation was 1/m * 1/m because I thought f(x1) probability to get to cell y is 1/m and also for f(x2)
therefore combining them is by multiplication.
