A = {x:x is a prime number}, Set A is`............`set. (Finite, Null, Infinite)

The set of the prime numbers is

1. The set of prime numbers less than 50 is: (A) a finite set (B) an infinite set (C) a singleton set (D) none of these.

State which of the following sets are finite sets or infinite. In case of finite set, mention the order of cardinal number (i) A=("x:x is a prime number and "x lt 15) (ii) B=(x:x in N, and 3x+2=11) (iii) C=(x:x in N and x^(2)-14x+3=0) (iv) D=(1,2,3,4....)

The set of whole number is a/an "_____" set . ( finite / infinite)

A = {x|x is a prime numbers le 100} B = {x| x is an odd numberc le 100} What is the ratio of the number of subsets of set A to set B?

A is a set of all the prime numbers less than 20, B is a set of all the even natural numbers less than 20 and C is a set of all the odd natural numbers. Which of the following is/are true statements ? (A) A nn B is a singleton set. (B) B and C are disjoint sets. (C) A nn C is an infinite set.

Check whether the following sets are equal ? (i) A = {The set of the first five elements of the periodic table} B={H, He, Li, Be, B} (ii) C = {x : x is a prime number} D = {x : x is an odd number}

State whether the following sets are finite or infinite:
