Define a function possible_rolls. The function has two parameters: The parameter n_sides represents the number of sides on the dice (from 1 - n_sides) and should have a default value of 6. The parameter n_dice represents the number of dice thrown together and should have a default value of 2 The function should return a Python list. Nested inside this list should be a list with every possible combination of rolls. The returned list should be sorted (see the below examples). possible_rolls(2, 2) # returns # [[1, 1], [1, 2], [2, 1], [2, 2]] possible_rolls(6, 1) # returns # [[1], [2], [3], [4], [5], [6]] possible_rolls(3, 2) # returns (adjusted for space) # [[1, 1], [1, 2], [1, 3], # [2, 1], [2, 2], [2, 3], # [3, 1], [3, 2], [3, 3]] possible_rolls() # returns (adjusted for space) # [[1, 1], [1, 2], [1, 3], [1, 4], [1, 5], [1, 6], # [2, 1], [2, 2], [2, 3], [2, 4], [2, 5], [2, 6], # [3, 1], [3, 2], [3, 3], [3, 4], [3, 5], [3, 6], # [4, 1], [4, 2], [4, 3], [4, 4], [4, 5], [4, 6], # [5, 1], [5, 2], [5, 3], [5, 4]
