2. c = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10} n(c) = 10

3. d ={ 1,2,4,5,10,20} n(d) = 6

4. d ={1,2,3,4} n(d) = 4

5. j = {M,A,T,H} n(j) =4

Answer 2

Given :   C = { x " x is a counting number from 1 to 10}

D = { x : x is factor of 20}

F = { x : 0 < x < 5 , x is a whole number }

J = { x : x is a distant letter in MATH }

To Find : list down the possible elements

determining the cardinality​

Solution:

 

C = { x " x is a counting number from 1 to 10}.

C = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

n(C) = 10 hence  cardinality = 10

 

D = { x : x is factor of 20}

D ={ 1,2,4,5,10,20}

n(D ) = 6 hence  cardinality = 6

F = { x : 0 < x < 5 , x is a whole number }

F ={1,2,3,4}

n(F) = 4   hence  cardinality = 4

J = { x : x is a distant letter in MATH }

J = {M,A,T,H}  

n(J) =4   hence  cardinality = 4
