Question

Putin ajutor va rog​

Answer 1

pt multimile A si C scriem numerele naturale intregi (adica numai numere pozitive) care se regasesc in intervalele mentionate, iar pt B scriem si numerele negative intregi dib respectivul interval.

A={1,2,3,4,5,6}

B={-3,-2,-1,0,1,2,3,4,5}

C={0,1,2,3,4}

card A= numarul elementelor multimii A

card A= 6, card B=9, card C= 5

AUB cuprinde elemelentele celor doua multimi

AnB cuprinde elementele comune ale celor doua multimi

A\B cuprinde elementele din A care nu se regasesc in B

AUB={-3,-2,-1,0,1,2,3,4,5,6}, card (AUB)= 10

BUC={-3,-2,-1,-0,1,2,3,4,5}=B, card (BUC)=9

AUC={0,1,2,3,4,5,6}, card (AUC)=7

AnB={1,2,3,4,5}, card (AnB)=5

AnC={1,2,3,4}, card (AnC)=4

BnC={0,1,2,3,4}, card (BnC)=5

A\B={6}, card (A\B)=1

A\C= multimea vida, card(A\C)=0

B\C={-3,-2,-1,5}, card (B\C)= 4

Answer 2

Răspuns:

Explicație pas cu pas:

A={1,2,3,4,5}

B={-3,-2,-1,0,1,2,3,4,5}

C={-2,-1,0,1,2,3,4}

Card A=5  ; Card B=9  ; Card C=7

Card (A∪B)=9 ; Card (B∪C)=9   Card(A∪C)=8

Card (A∩B)=5 ; Card (A∩C)=4  Card(B∩C)=7

Card (A\B)=0  Card (A\C)=1  ; Card (B\C)=2
