Question

a se determine multimile x si y stiind ca sunt indeplinite simultan conditiile: a). xintersectaty= {1,2,3,} b) x\y = {5} c) y inclus {1,2,3,4,5,6}

Answer 1

a) X∩Y= {1,2,3,} ⇒elementele multimii se gasesc si in x si in y
b) X\Y = {5}⇒ 5 se gaseste numai in x
c) Y⊂ {1,2,3,4,5,6}

X= {1,2,3,5}
Y= {1,2,3,4,6}⇒ Y⊂ {1,2,3,4,5,6}
