Answer:
120
Step-by-step explanation:
nCk or C(n, k) are ways to write the "combinations" function. That function tells you how many combinations of n things there are when they are taken k at a time.
Here, you have 10 vegetables, and you want to count the number of ways you can take 3 at a time. You are being asked to find the value of 10C3, or C(10,3). You do this by putting 10 where n is in the formula, and 3 where k is. Then do the arithmetic.
10C3 = (10!)/(3!(10-3)!) = 10·9·8/(3·2·1) = 5·3·8 = 120
120 3-vegetable plates may be made.
