Question

13. (3pts) An engineer wishes to investigate the effect of adhesive type, conductor material, cure time, and types ot post coatings on bond strength when mounting an integrated circuit (IC) on a certain substrate. Two adhesive types, two conductor materials, three cure times, and four types of IC post coatings are under consideration. H many ways can these four factors be chosen?

Answer 1

total number of choices =N(number of adhesive type)*N(type of conductor material)*N(type of cure time)*N(type of post coatings)=2*2*3*4=48
