Probability question - help please!!?

A bag contains 3 red blocks, 2 blue blocks, and 6 yellow blocks. If you draw one single block, then n(S) is:a) 3b) 1c) 6d) 11

D. 11

can you please explain what n(S) is

Unfortunately, your question is meaningless because you haven't defined what n(S) is supposed to mean.I would presume, though, that S might be the random variable that represents the drawing of one single block.n(S) could be the number of possible outcomes for S. Then the answer would be A: 3.n(S) could also refer to the lowest common denominator of all possible probabilities (which is sometimes referred to as the number of possible events). Then the answer would be D: 11.
