1.Question 1Consider the following set: {"A","A"}, what will the result be when the set is created? 1 point {"A","A"} {"A"} 2.Question 2What is the result of the following: type(set([1,2,3]))1 pointsetlist3.Question 3What method do you use to add an element to a set?1 pointextendaddappend4.Question 4What is the result of the following operation : {'a','b'} &{'a'}1 point{'a'}{'a','b'}

The result will be {"A"}. In a set, duplicate elements are not allowed, so it will only keep one "A".

The result of type(set([1,2,3])) will be <class 'set'>. The type() function is used to determine the type of the object. Here, it is used to determine that set([1,2,3]) is a set.

The method used to add an element to a set is add(). The extend() and append() methods are not applicable to sets.

The result of the operation {'a','b'} &{'a'} will be {'a'}. The & operator is used for set intersection, which returns the common elements in both sets. In this case, 'a' is the common element.
