Will give brainliest!! Please help

A jar contains 3 colors of push pins. Carlin reached into the jar five different times and randomly chose some push pins, recorded their color, and then replaced them. The results are shown in the table below.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
