(a) In how many different ways can the sample be selected? ways (b) How many samples contain exactly 3 defective transistors? samples (c) How many samples do not contain any defective transistors? samples

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
