Question

What is the union sets M= (1,7,10,11,15) and N=(5,15)?

Answer 1

Answer: (1,5,7,10,11,15)

To get the union of two sets of numbers, all you do is combine the numbers from least to greatest. If a number repeats in the 2 sets, you only put it once.

Answer 2

M ∪ N = (1, 5, 7, 10, 11, 15)

Explanation:

A set is said to be a union of two sets A and B which has the elements present in the set A and B or in both. Union of two sets A and B will be denoted by A ∪ B.

For the two given sets M = (1, 7, 10, 11, 15) and N=(5, 15), their union M ∪ N will contain all the elements from the two sets but none of the elements will be repeated.

Therefore, M ∪ N = (1, 5, 7, 10, 11, 15)
