In the game of​ roulette, a wheel consists of 38 slots numbered​ 0, 00,​ 1, 2,..., 36. To play the​ game, a metal ball is spun around the wheel and is allowed to fall into one of the numbered slots. If the number of the slot the ball falls into matches the number you​ selected, you win​ $35; otherwise you lose​ $1.

Decide if the situation involves permutations, combinations, or neither. Explain your reasoning. The number of ways 18 people can line up in a row for concert tickets. Does the situation involve permutations, combinations, or neither? Choose the correct answer below. A. Combinations. The order of the 18 people in line does not matter. O B. Neither. A line of people is neither an ordered arrangement of objects, nor a selection of objects from a group of objects. OC. Permutations. The order of the 18 people in line matters.
