Let A={x:x is a square of a natural number and x is less than 100} and B is a set of even natural numbers. What is the cardinality of `AnnB`?

Let A = (x : x is a square of a natural number and x is less than 100) and B is a set of even natural numbers. What is the cardinality of A cap 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.

If A={x:x is a natural number multiple of 3} and B={x:x is a natural number less than 6} then A∩B.

A = {x: x ia a natural number less than 8} Write a subset of A containing all even numbers in A.

IF A={x:x is a natural number less than is 6} B={x:x is a prime number which is a divisor of 60} C={x:x is an odd natural number less than 10} D={x:x is an even natural number which is a divisor of 48} Then write roster form for all above sets and find B cap C

IF A={x:x is a natural number less than is 6} B={x:x is a prime number which is a divisor of 60} C={x:x is an odd natural number less than 10} D={x:x is an even natural number which is a divisor of 48} Then write roster form for all above sets and find D-B

IF A={x:x is a natural number less than is 6} B={x:x is a prime number which is a divisor of 60} C={x:x is an odd natural number less than 10} D={x:x is an even natural number which is a divisor of 48} Then write roster form for all above sets and find A cup B

IF A={x:x is a natural number less than is 6} B={x:x is a prime number which is a divisor of 60} C={x:x is an odd natural number less than 10} D={x:x is an even natural number which is a divisor of 48} Then write roster form for all above sets and find A-D

Answer, whether the following statements are true or false. Give reasons. The set of even natural numbers less than 21 and the set of odd natural numbers less than 21 are equivalent sets.

If A is the set of even natural numbers less than 8 and B is the set of prime numbers less than 7, then the number of relations from A to B is :
