A) {(a, c), (a, d)}
B) {(a, b), fc d)}
C) {(c a), (d, a)}
D) {(a, c), (a, d). (b, d)}
Correct Answer: A
Solution :
Given that, A ={a, b, c}, B ={b, c, d} and C ={a, d, c} Now, \[A-B=\{a,\text{ }b,\text{ }c\}-\{b,\text{ }c,\text{ }d\}\] \[=\{a\}\] and \[B\cap C=\{b,c,d\}\cap (a,d,c)\] \[=\{c,d\}\] \[\therefore \] \[(A-B)\times (B\cap C)=\{a\}\times \{c,d\}\] \[=\{(a,c),(a,d)\}\]You need to login to perform this action.
