If we have information about workers' marginal products, then total and average product can be found by

Summing the marginal values to find the total and dividing it by the number of workers to get the average.

Explanation:

As we know that the marginal product of labor would be the extra amount of the product that is received by adding one or more labor in the process of the production. Now if we add the marginal amounts so we can get the total product

Also the average product could be determined by dividing the total product by its number of workers

Therefore the above is the answer
