Question

2. For the list a - 1-1,8,21,tuple b-(5,1,-3), and ndarray c -np.array (11,1,21) determine the results of the following expressions and place them in the spaces on the right of the table. If the expression would return an error, write "error" as the result. Note that each expression is independent of the others.
