The larger the sample size (number of people asked), the more accurate the results generally are, due to the law of large numbers.
- (2x+y+2z) = -(2(x+z) + y)
To evaluate the combination we proceed as follows:
21C3
Given nCk we shall have:
n!/[(n-k)!k!]
thus plugging the values in the expression we get:
21!/[(21-3)!3!]
=21!/(18!×3!)
=1330
Answer: 1330
The answer is c and then b and then a
