This is the online documentation of std.random.dice() (DMD 2.052) (note the
missing rnd generator agument):
http://www.digitalmars.com/d/2.0/phobos/std_random.html#dice

auto x = dice(0.5, 0.5);   // x is 0 or 1 in equal proportions
auto y = dice(50, 50);     // y is 0 or 1 in equal proportions
auto z = dice(70, 20, 10); // z is 0 70% of the time, 1 30% of the time,
                           // and 2 10% of the time


But this generates several compile bugs:

import std.random;
void main() {
    dice(0.5, 0.5);
}


While this compiles and runs:

import std.random;
void main() {
    auto rnd = Xorshift(1);
    dice(rnd, 0.5, 0.5);
}


This looks like a documentation bug, but I prefer to see it as an enhancement
request.
