Math Problem Statement
Solution
The image contains a logic problem involving three statements:
- : It is Saturday.
- : Reuben is practicing basketball.
- : Reuben is out of breath.
There are two arguments given in the table, where the goal is to express each argument in symbolic form and determine whether the argument is valid.
Argument (a)
Argument:
- If it is Saturday, then Reuben is practicing basketball.
- If Reuben is practicing basketball, then Reuben is out of breath.
- Therefore, if it is Saturday, then Reuben is out of breath.
We need to represent this in symbolic form:
- "If it is Saturday, then Reuben is practicing basketball" is .
- "If Reuben is practicing basketball, then Reuben is out of breath" is .
- Conclusion: "If it is Saturday, then Reuben is out of breath" is .
This forms a classic hypothetical syllogism:
So the symbolic form for argument (a) should be:
In the choices, this corresponds to the form found in the third option for argument (a).
Validity:
This argument is valid, as it follows the hypothetical syllogism rule.
Argument (b)
Argument:
- If it is Saturday, then Reuben is practicing basketball.
- Reuben is practicing basketball.
- Therefore, it is Saturday.
Symbolically:
- "If it is Saturday, then Reuben is practicing basketball" is .
- "Reuben is practicing basketball" is .
- Conclusion: "Therefore, it is Saturday" is .
This commits the fallacy of affirming the consequent. Just because (Reuben practicing basketball) is true does not necessarily imply that (it being Saturday) is true.
So the symbolic form is:
This corresponds to the second option for argument (b).
Validity:
This argument is not valid because it commits the affirming the consequent fallacy.
Summary:
- Argument (a): Valid, symbolic form is , , therefore .
- Argument (b): Invalid, symbolic form is , , therefore .
