Find the cardinality of the set Enter ALEPH0 for N0 A m m n

Find the cardinality of the set. (Enter ALEPH_0 for N_0.) A =m {m, n, o, ..., t}

Solution

Given that

A = { m , n , o , .........., t }

We know that

Cardinality of set is defined as number of elements in given set

Hence ,

A = { m , n , o , p , q , r , s , t }

Number of elements in set A = 8

Cardinality of set A = 8

Therefore ,

n(A) = 8
