Question

Carla can choose two of her three pairs of sneakers to take to a track meet. If the pairs of sneakers are called A, B, and C, which choice represents the sample space, S, for the event?

S = {ABC}
S = {ABC, CAB}
S = {AB, AC, BC}
S = {AB, BA, AC, CA, BC, CB}

Answer 1

S = {AB, AC, BC}

Order doesn't matter when choosing two pairs, so the three possible 2-element combinations are AB, AC, and BC.
