Question

Расположи 2 элемента в множествах A B C так чтобы каждое число из них содержался Соответственно а)по 2 элемента б)2,2 и 1 элемент в) 2,1,1 г)2,1,0 элементов д)2,2,0 элементов е)по 1 элементу

Answer 1

А) A = B = C = {1; 2}
б) A = B = {1; 2}; C = {1}
в) A = {1; 2}; B = C = {2}
г) A = {1; 2}; B = {1}; C = пустое множество
д) A = B = {1; 2}; C = пустое множество
Если я правильно поняла задание.

Answer 2

I will try to answer your question in detail. To arrange 2 elements in the sets A, B, C so that each number from them is contained respectively:

a) 2 elements each: One possible way is to let A = {1, 2}, B = {2, 3}, C = {1, 3}. Then each set has 2 elements and each number from 1 to 3 is contained in two sets.

b) 2, 2, and 1 element: One possible way is to let A = {1, 2}, B = {2, 3}, C = {4}. Then A and B have 2 elements each, C has 1 element, and each number from 1 to 4 is contained in one or two sets.

c) 2, 1, and 1 element: One possible way is to let A = {1, 2}, B = {3}, C = {4}. Then A has 2 elements, B and C have 1 element each, and each number from 1 to 4 is contained in one set.

d) 2, 1, and 0 elements: One possible way is to let A = {1, 2}, B = {3}, C = {}. Then A has 2 elements, B has 1 element, C has 0 elements, and each number from 1 to 3 is contained in one set.

e) 1 element each: One possible way is to let A = {1}, B = {2}, C = {3}. Then each set has 1 element and each number from 1 to 3 is contained in one set.
