SOLUTION

CORRECT QUESTION

If A={1,2,3} & B = { 2,3,4} then find A-B and B-A

CONCEPT TO BE IMPLEMENTED

DIFFERENCE OF SETS

If A & B are two sets then their difference is denoted by A - B and defined as

\sf{A - B = \{x : x \in A \: , \: x\notin \: B \}}A−B={x:x∈A,x∈

/

B}

EVALUATION

Here the given two sets are

A= { 1,2,3 } & B = { 2,3,4}

∴ A - B = { 1 }

∴ B - A = { 4 }
