Question

If A is a set of letters in the word "MADAM '.Then find number of sub sets of set A

Answer 1

Step-by-step explanation:

16 because here power set formula is applied i.e, 2 resto the power n here n = 4 , it was to be 5 but in a set no elements are repeated so it's been now 2 to the power 4 means it's 16 ....

Thank you

Answer 2

Concept:

The mathematical representation of a group of various objects is called a set. A set contains elements or members, which can be any type of mathematical object, including variables, other sets, numbers, symbols, points in space, lines, and other geometric shapes. A set with a single element is a singleton, while a set with no elements is an empty set. A set can either be infinite or have a finite number of elements. If all of the elements in two sets are identical, then the sets are equal.

Given:

MADAM

Find:

No. of subsets of MADAM

Solution:

No. of distinct letters in MADAM  is 3 i.e M,A,D

So, A={M,A,D}

n(A)=3

no. of subsets  of set A=2³

                                      =8

Therefore, the no. of subsets of MADAM is 8
