Question

If C = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} and D = {numbers not divisible by 2 from 1 to 10}, what is CintersectionD?

Answer 1

is {2,4,6,8,10}

Answer 2

D are numbers not divisible by two, so the opposite of ^.

Answer 3

C inter D =
{1,3,5,...2n+1...10}

Answer 4

Yes, except the 10; the odd numbers between 1 and 9.

Answer 5

oh {1,3,5,7,9} ?? @Valpey

Answer 6

yeah not 10 opps

Answer 7

Oh okayy (:

Answer 8

The point is that C contains only natural numbers between 1 and 10, and D contains all (presumably real) numbers between 1 and 10. The intersection is all the numbers that are both in C and D.

Answer 9

ohhh i get now. thankss again :)

Answer 10

I mean D contains all (presumably real) numbers between 1 and 10 which aren't even.
