    A variation of this using the cmp built-in function

    n = int(raw_input().strip())
arr = map(int,raw_input().strip().split(' '))

NEG, EQUAL, POS = -1, 0, +1

D = {NEG : 0, EQUAL: 0, POS: 0}

for i in arr:
    D[cmp(i, 0)] += 1

for k in (POS, NEG, EQUAL):
    f = 1.0 * D[k] / n
    print "%.6f" % f
