1.	Given that A = { 5,7,11,13 } and B = { 2,3,5,7} and C = { x : x is an integer and -3 < x < 3 }then find (I) B U C (ii) A intersection B (iii) State whether sets A and B are equal or equivalent? (iv) State whether sets A and C are joint or disjoint?
Answer» ANSWER: I)BUC={-2,-1,0,1,2,3,5,7} ii)Aint.B={5,7} III)equivalent - CUZ same no. of elements iv)DISJOINT - cuz no common element Step-by-step explanation: A={5,7,11,13} B={2,3,5,7} C={-2,-1,0,1,2}

Given that A = { 5,7,11,13 } and B = { 2,3,5,7} and C = { x : x is an integer and -3 < x < 3 }then find (I) B U C (ii) A intersection B (iii) State whether sets A and B are equal or equivalent? (iv) State whether sets A and C are joint or disjoint?

Answer»

I)BUC={-2,-1,0,1,2,3,5,7}

ii)Aint.B={5,7}

III)equivalent - CUZ same no. of elements

iv)DISJOINT - cuz no common element

Step-by-step explanation:

A={5,7,11,13}

B={2,3,5,7}

C={-2,-1,0,1,2}
