Question

A={a| a > 1,a is an integer write with reason and solve,set is finite or infinite​

Answer 1

Answer:

(i) A= { x:x is a multiple of 5, x∈N } ={5,10,15,20,...}

∴A is an infinite set.

(ii) B= { x:x is an even prime numbers }. The only even prime number is 2.

∴B={2} and hence B is a finite set.

(iii) Let X be the set of all positive integers greater than 50. Then X={51,52,53,...}

∴X is an infinite set.
