Question 238327: Let A = {1,3,5,6,7}. Find n(A).
Answer by Edwin McCravy(20086)   (Show Source):
You can put this solution on YOUR website! Let A = {1,3,5,6,7}. Find n(A).
n(A) just means how many members or elements A has.
It has 5 members or elements, so n(A) = 5. Pretty easy, huh?
Just count them!
