Can someone explain to me why the intersection of two infinite sets is not always an infinite set, but the union of two infinite sets is?

Set S contains the elements = { 1, 2, 3, 4, 5, 6, 7, 8}. From this set, John takes sets of 6-digits each and sums all the possible 6-digit numbers that can be formed with those sets. What is the HCF of all these sums?

Statistics
Why do we need to distinguish between strong and weak correlation of data sets using best-fit lines? When a correlation has been established between the two data sets, how is it linked to causality? Please provide examples to support your answer.
