What is the cardinality of each set?
no ideas? How many members in each set?
The cardinality of a set refers to the number of elements in that set. Here are the cardinalities of the given sets:
A = {distinct letters in the word "miss"} : The distinct letters in the word "miss" are 'm', 'i', and 's'. So, the cardinality of set A is 3.
B = {15} : The set B contains only one element, which is 15. So, the cardinality of set B is 1.
C = {m, i, s} : The set C contains three elements, which are 'm', 'i', and 's'. So, the cardinality of set C is 3.
D = {2 + 1} : The set D contains the result of the sum 2+1, which is 3. So, the cardinality of set D is 1.
E = {three} : The set E contains only one element, which is the word "three". So, the cardinality of set E is 1.
F = {3} : The set F contains only one element, which is the number 3. So, the cardinality of set F is 1.
To find the cardinality of a set, we need to count the number of elements in the set. Let's go through each set and count the number of elements:
A = {distinct letters in the word miss}
In the word "miss", there are three distinct letters: m, i, and s. So, the cardinality of set A is 3.
B = {15}
Set B contains only one element, which is 15. So, the cardinality of set B is 1.
C = {m, i, s}
Set C contains three elements: m, i, and s. So, the cardinality of set C is 3.
D = {2 + 1}
The set D contains only one element, which is the result of the operation 2 + 1. Therefore, the cardinality of set D is 1.
E = {three}
Set E contains one element, which is the word "three". So, the cardinality of set E is 1.
F = {3}
Set F contains only one element, which is the number 3. Therefore, the cardinality of set F is 1.
To summarize:
Cardinality of set A: 3
Cardinality of set B: 1
Cardinality of set C: 3
Cardinality of set D: 1
Cardinality of set E: 1
Cardinality of set F: 1
