input: Write a python function to filter numbers that are divisible by both 3 and 5 from a list.
  assert filter_divisible([0, 1, 3, 5, 6, 9, 10, 15, 30]) == [0, 15, 30]
  assert filter_divisible([2, 4, 7, 11, 14, 20, 25]) == []
  assert filter_divisible([45, 60, 75, 90, 105]) == [45, 60, 75, 90, 105]
output: def filter_divisible(numbers):
      return [num for num in numbers if num % 3 == 0 and num % 5 == 0]
