If A is the set of even natural numbers less then 8 and B is the set of prime numbers less than 7, then the number of relations from A to B is
(a) 29
(b) 92
(c) 32
(d) 29 - 1
The correct option (a) 29
Explanation:
Here A = {2, 4, 6} and B = {2, 3, 5}
∴ A x B contains 3 x 3 = 9 elements
∴ No of relations = 29
