Set a =0,1,2,...

Question

Set a=(0,1,2,3,4,5,6,7,8,9) set b=(0,1,2,3,4) set c=(5,6,7,8,9)

State true or false in the given statement

Cardinality of set a b and c 10,5 and 5 respectivily

Open in App

Solution

Yes, the given statement is true.

The cardinality of a set is a measure of the number of elements of the set.

Set A has 10 elements, Set B has 5 elements and Set C has 5 elements.

Thus given statement is true.
