Question

! If A is the set of the divisions of the number 15.
B is the set of prime numbers smaller than 10
and C is the set of even numbers smaller than 9,
then (AUC) n Bis the set
(a) {1, 3, 5} (b) {1, 2, 3} (c) {2} (d) {2,5}​

Answer 1

Answer:

Here your answer...

A = { 1 , 3 , 5 , 15 }

B = { 2 , 3 , 5 , 7 }

C = { 2 , 4 ,6 ,8 }

then,

AUC = { 1 , 2 , 3 , 4 , 5 , 6 , 8 , 15 }

Now,

( AUC ) n B = { 1, 2, 3, 4, 5, 6, 8 , 15 } n { 2, 3, 5, 7 }

= { 2, 3 , 5 } ans.......

I hope it will help you.........

Answer 2

Answer:

{2,3,5}

Step-by-step explanation:

GIVEN THAT A IS DIVISORS OF 15

{A}={1,3,5,15}

GIVEN THAT B IS SET OF PRIME LESS THAN 10

{B}={2,3,5,7}

GIVEN THAT C IS SET OF EVEN LESS THAN 9

{C}={2,4,6,8}

NOW GIVEN THAT (AUC)nB

=> AUC=(1,2,3,4,5,6,8,15)

=> AUCnB={2,3,5}
