Translate the following arguments into symbols and prove their validity using rules of inference. 1. A student in this class has not read the first module. Everyone in this class passed the first exam. Therefore, someone who passed the first exam has not read the first module. Hint: Use the following symbols. C(x):x is in this class. B(x):x has read the book. P(x):x has passed the first exam. 2. Everyone in the class has a graphing calculator. Everyone who has a graphing calculator understands the trigonometric functions. Therefore, Mickey, who is in the class, understands the trigonometric functions. Hint: Use the following symbols. C(x):xis in this class. G(x):x has a graphing calculator. T(x):x understands trigonometric functions. y = Mickey

Question
Transcribed Image Text:Translate the following arguments into symbols and prove their validity using
rules of inference.
1. A student in this class has not read the first module.
Everyone in this class passed the first exam.
Therefore, someone who passed the first exam has not read the first
module.
Hint: Use the following symbols.
C(x):x is in this class.
B(x):x has read the book.
P(x): x has passed the first exam.
2. Everyone in the class has a graphing calculator.
Everyone who has a graphing calculator understands the trigonometric
functions.
Therefore, Mickey, who is in the class, understands the trigonometric
functions.
Hint: Use the following symbols.
C(x):x is in this class.
G(x):x has a graphing calculator.
T(x):x understands trigonometric functions.
y = Mickey
