Question 12: Given two sets: (A = left{ {} right.)Tuan, Dung(left. {} right}), (B =left{ {} right.)orange, apple, guava(left. {} right}.) How many sets can be written, each consisting of one element of set A and one element of set B ?

Quiz Question 12: Given two sets: \(A = \left\{ {} \right.\)Tuan, Dung\(\left. {} \right\}\), \(B =\left\{ {} \right.\)orange, apple, guava\(\left. {} \right\}.\) How many sets can be written, each consisting of one element of set A and one element of set B ?





Think and answer the question before looking at the answer

The sets consisting of 1 element of set A and 1 element of set B are:

{Tuan, orange}; {Tuan, Guava}; {Tuan, apple}; {Dung, orange}; {Dung, guava}; {Dung, apple}

So there are 6 sets satisfying the problem.
