It can be.A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. So 365 is a decimal number and it is a cardinal number representing the number of days in an ordinary year.

Count the number of distinct elements in the set.

The cardinal number of a set is the number of elements in the set. Example: the cardinal number of the set {6, prune, 675, biscuit, London} is 5, since the set contains five elements. If a set contains repeated elements, they should only be counted once. Example: the cardinal number of the set {6, 7, 3, 4, 4, 7} is 4 (not 6) since the fours and sevens are only counted once.

The main cardinal number for 7 is 7, but 1 is also a cardinal number for 7 in this case.

I feel like a better explanation is that the answer is 26. I assumed that you were asking for {x|x, as long as x is a letter of the alphabet}. The cardinal number is basically just the number of terms in the set (it has to be distinct).

The cardinality of a set is its size. For instance, since the set G contains 4 elements, then its cardinality is 4. So if the set has a finite number of elements (meaning it is a finite set), you can find its cardinality, otherwise you cannot (meaning it is an infinite set).

No. The number of subsets of that set is strictly greater than the cardinality of that set, by Cantor's theorem. Moreover, it's consistent with ZFC that there are two sets which have different cardinality, yet have the same number of subsets.
