If A={x:x=odd number less than 3, and xϵN} then set A is
a singleton set
a null set
an infinite set
none of the above
Given,
A={x:x=odd number less than 3, and xϵN}
⇒A={1}
⇒ A is a singleton set.
If A = {set of odd numbers less than 3}, then A is
If U = {x : x ϵ N}, A = {x : x = 2n, n ∈ N} and B = {x : x is a prime number}, then A ∩ B is ___.
If A = {set of prime numbers}, then A is _____.
