Ingots composed of copper alloys were poured into one of three mold types with either a transverse or a longitudinal orietation. From each ingot , five tensile specimens were obtained at varying distances (10,35,60,85,100) from the ingot chill face and yield strength was determined.
A. How many stength measurements will be obtained if the experiment includes one ingot for each mold type-orientation combination?
B. Suppose three of the ingots will be selected for further testing at the 100mm distance. How many samples of three ingots can be selected from the total number of ingots in the experiment?
C. Calculate the probability that the sample selected includes the three highest tensile strengths among all the ingots in the experiment
