Question

What is the cardinal number of M = {vowels in the word "MATHEMATICS"}?
(its not 2)

Answer 1

Answer:

The CARDINALITY of a set is the number of elements in the set.

Step-by-step explanation:

As because MATHEIC=7

Answer 2

The cardinal number of M = 3

Given: M = {vowels in the word "MATHEMATICS"}  

To find: The cardinal number of M

Solution:

From given data

M = { A, E, A, I }         [ ∵ vowels = A, E, I, O, U}  

here we take only one A

⇒ M = {A, E, I}  

Note: Number of elements in a set is known as Cardinal number of the Set which denoted by "n"  

Here number of elements in M = 3

Therefore, cardinal number of M = 3

we can also write it as n(M) = 3
