Question

If A = {1,3}, B = {2,3} and C = {3,5), then n{(A x B) U (B x C)} i​

Answer 1

Answer:

The value of n(set) will be 7

Step-by-step explanation:

Given, A={1,3}

B={2,3} ,and

C={3,5} so the value of A×B={(1,2),(1,3),(3,2),(3,3)} and

that of , B×C={(2,3),(2,5),(3,3),(3,5)} so,

uniting both the sets of Cartesian product we get

(A×B) U (B×C)={(1,2),(1,3),(2,3),(2,5),(3,2),(3,2),(3,5)}

so now cardinal number of above set will be

n[(A×B)U(B×C)]=7
