Final answer:
The student's statement contains a logical fallacy and is not necessarily true because discrete mathematics can be part of other majors' requirements or electives. It is important to distinguish that while discrete mathematics is commonly associated with computer science, it is not exclusive to it.
Step-by-step explanation:
The student's question involves a logical fallacy known as affirming the consequent. The argument states that every computer science major takes discrete mathematics, Natasha is taking discrete mathematics, and therefore concludes that Natasha must be a computer science major. However, this reasoning is not valid because taking discrete mathematics does not exclusively imply that a person is a computer science major. While it's common that such a mathematics course is a requirement for a computer science degree, discrete mathematics could also be required or elective in other disciplines, such as mathematics, engineering, or economics.
It's important to remember that while computer science is deeply intertwined with mathematics, the two fields are distinct. Discrete mathematics is a branch that deals with mathematical structures that are fundamentally discrete rather than continuous. It has a wide array of applications not just in computer science, but also in other fields where quantization, counting, and logical thinking are necessary.
