Answer:
I believe it's B, 10
Step-by-step explanation:
well first you find where the points would meet. if you count over three, that's where they line up, and then you count up to the dot itself, which would be 7 more. 7+3 = 10 :D
<u>Question 1</u>
The complement of set B is all the elements in S but that are not in B, which is
.
We want to find the intersection of set A and the complement of set B, which is the set of all elements that both sets contain.
This is {2, 9, 10, 12}, meaning there are 4 elements.
<u>Question 2</u>
Following a similar logic as the last problem, the complement of set A is
.
Therefore, the desired set is
, and thus there are 6 elements.
