Question

Let A = {1, 2, and B = 3, 4, 5). Then the number of relations from A to B is (a) 6 (b) 5 (c) 32 e 64​

Answer 1

Answer:

option d

Step-by-step explanation:

$a = {1.2} \\ b = 3.4.5 \\number \: of \: elements \: in \: set \: a = n(a)= 2 \\ number \: of \: elements \: in \:set \: b = n(b) = 3 \\ number \: of \: relation \: from \: a \: to \: b = {2}^{n(a) \times n(b) } \\ {2}^{2 \times 3 } = {2}^{6} = 64$
