Alyssa has four marbles: a red one, a blue one, a green one, and a yellow one. In how many different ways can she form a set consisting of some of the marbles if she must choose at least one marble? (In a set of chosen marbles, it does not matter in what order she chose the marbles.)


pls give me a nudge....

\(\text{She picks 1 to 4 marbles}\\ \text{There are 4 distinct marbles in total so if she picks $k$ marbles $\\$ there are $\dbinom{4}{k}$ ways to pick them}\\ \text{So how many total ways are there to pick the marbles?}\)
