Question

The mathematical expression 9 & T means:

a) 9 Intersection T
b) 9 Union T
c) 9 is not an element of T
d) 9 is an element of T

Answer 1

The mathematical expression 9 & T means that 9 is not an element of T. Hence the correct answer is option C

Step-by-step explanation:

The mathematical expression 9 & T means that 9 is not an element of T. This is option c) 9 is not an element of T.

To understand this, let's consider an example. If T is a set of numbers {1, 2, 3, 4}, then 9 is not part of set T because it is not one of the elements in set T. So, the expression 9 & T would evaluate to false.

Therefore, the correct answer is c) 9 is not an element of T.
