What form of deductive reasoning is used in the given argument? If a number ends in 0, then it is divisible by 10. If a number is divisible by 10, then it is divisible by 5. If a number ends in 0, then it is divisible by 5. A. Law of detachment B. Law of syllogism C. Law of contrapositive D. Identification of counterexample

Respuesta :

Answer:

B. Law of syllogism.

Explanation:

The deductive reasoning behind the set of arguments is the Law of Syllogism, defined by the following logical rule:

1) [tex]\alpha \Rightarrow \beta[/tex]

2) [tex]\beta \Rightarrow \gamma[/tex]

Hence,

3) [tex]\alpha \Rightarrow \gamma[/tex]

In this case, we have three simple propositions:

[tex]\alpha =[/tex] A number ends in 0.

[tex]\beta =[/tex] A number is divisible by 10.

[tex]\gamma =[/tex] A number is divisible by 5.

The reasoning represented by the consecutive arguments is:

1) If a number ends in 0, then it is divisible by 10.

2) If a number is divisible by 10, then it is divisible by 5.

Hence,

3) If a number ends in 0, then it is divisible by 5.
