Final answer:
The symbol for the intersection of two sets is option b) ∩, which includes all elements common to both sets.
Step-by-step explanation:
The symbol that represents the intersection (∩) between two sets is option b) ∩. The intersection of two sets includes all the elements that are common to both sets. To illustrate this with an example, imagine we have Set A and Set B. If Set A = {2, 4, 14, 16, 18} and Set B = {14, 16, 18, 19}, then the intersection of Set A and Set B (denoted as A ∩ B) is {14, 16, 18}, because those are the numbers that appear in both sets.
An easy way to remember this is to think of the intersection symbol ∩ as an 'n' for 'AND', which implies you are looking for elements in A AND B. Consequently, the answer to the question about which symbol represents the intersection between two sets is indeed option b) ∩.
