Answer 1

Respuesta:

. nA() = nA(-B)+nA(Ç B) = 14 + x + x = 14 + 2x 9. Chapter Functions 1. ... (i) C= B¢ (ii) Equivalent sets are C= {3, 4, 5, 6, 7} and D = {odd numbers less than ... set = {x :8 < x < 15} Given set with respect to set A is A¢. n(A–B) = 14+x, n(B–A)=3x ... n(A) + n(B)-n(AÇ B) = 14 + 2x + 4x – x = 14 + 5x = 14+5 (7)=14+35 = 49 \ n(AÈB) ...
