Question

2.) Classify the following as an empty set or a singleton set or a finite set.
a. A = {x:x € 2,0 b. B = {set of all natural satellites of the earth}
c. X = {set of all women prime ministers of India}
d. Y = {set of vowels in the word 'follow'}
e. P = {set of vowels not in the word 'Constantinople'}
f. Q = {x:x € N and x is a multiple of 11 between 100 and 110}
g. A = {x: X € Z, -1 h. B = {set of vowels not in word equitorial}
i. C = {x:X N and x is prime number, 23 < x < 29}

Answer 1

Answer:

of vowels not in the word 'Constantinople'}

f. Q = {x:x € N and x is a multiple of 11 between 100 and 110}

g. A = {x: X € Z, -1 h. B = {set of vowels not in word equitorial}

i. C = {x:X N and x is prime number, 23 < x < 29}

Answer 2

Answer:

The set of Natural number is

N={1,2,3,4,5,...}

Clearly, natural number are positive numbers.

Therefore, Set A does not contain any element.

∴A={x∣x is negative natural number}=ϕ

i.e A is empty.
