Question

5. Пусть М = {4, 2, 5}, P = {4, 2, 3, 10, 6}, K = {3, 10, 6}. Запишите с помощью фигурных скобок или знака ø: а) пересечение M и K; б) пересечение K и P; в) объединение M и P; г) объединение M и K; д) объединение K и P

Answer 1

Ответ:

а) пересечение M и K; = ø

б) пересечение K и P; = {3,10,6}

в) объединение M и P; = {2,3,4,5,6,10}

г) объединение M и K; = {2,3,4,5,6,10}

д) объединение K и P = {2,3,4,6,10}

Answer 2

Answer in detail. 5. Let M = {4, 2, 5}, P = {4, 2, 3, 10, 6}, K = {3, 10, 6}. Write using curly brackets or the sign ø: a) intersection of M and K; b) intersection of K and P; c) union of M and P; d) union of M and K; e) union of K and P.

The answer is:

a) The intersection of M and K is the set of elements that belong to both M and K. In this case, it is the empty set, denoted by ø, because M and K have no common elements.

b) The intersection of K and P is the set of elements that belong to both K and P. In this case, it is {10, 6}, because these are the only two elements that are in both sets.

c) The union of M and P is the set of elements that belong to either M or P, or both. In this case, it is {4, 2, 5, 3, 10, 6}, because these are all the elements that are in either set.

d) The union of M and K is the set of elements that belong to either M or K, or both. In this case, it is {4, 2, 5, 3, 10, 6}, because these are all the elements that are in either set.

e) The union of K and P is the set of elements that belong to either K or P, or both. In this case, it is {3, 10, 6, 4, 2}, because these are all the elements that are in either set.
