Answer:

Combination; number of ways = 15.

Step-by-step explanation:

Given that there are 6 people in the contest. So it means n = 6.

Two winners each win gift cards. So it means r = 2.

Each gift card is same, so both persons are equally important. It means the order does not matter here, so it is the case of Combinations. We will use nCr formula.

Total number of ways = 6C2 = (6*5)/2 = 15.

Hence, Combination; number of ways = 15.
