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

M ∪ N = (1, 5, 7, 10, 11, 15)

Step-by-step 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)
