Use the table below to answer the following question(s) .
Below is a spreadsheet for Stone Age Surfboards.

Assume that the finishing time for a pair of Rockwell surfboards is triangular with a minimum value of 1.4, a most likely value of 1.5, and a maximum value of 1.8 and that finishing time for a pair of Limestone surfboards is also triangular with a minimum value of 1.8, a most likely value of 2.0, and a maximum value of 2.4.The number of trials per simulation is equal to 5000.
-How often will overtime be needed if 4.5 Rockwell and 9.0 Limestone surfboards, the optimal solution, are scheduled each day?

A) more than 60%
B) more than 87%
C) more than 75%
D) more than 52%
