Question

49.Satish and his friend Rajat are interested to know the number of symmetric relations defined on both the sets A and B, separately. Satish decides to find the symmetric relation on set A while Rajat decides to find symmetric relation on set B. What is difference between their
results?
(a) 1024 b) 210 (15)
(c) 2¹0(31)
(d)2¹0 (63)

Answer 1

Answer:

Step-by-step explanation:Therefore, A has 5 elements and B has 4 elements. Therefore, total number of symmetric relation on set A is 25(5+1)2 2 5 ( 5 + 1 ) 2 = 215 . And total number of symmetric relation on set B is 24(4+1)2 2 4 ( 4 + 1 ) 2 = 210
