Answer:
a) the Statement is Invalid
b) the Statement is Invalid
Explanation:
a)
lets Consider, s: student of my class
A(x): Getting an A
Let b: john
I have a student in my class who is getting ab A: Зs, A(s)
John need not be the student i.e b ≠ s could be true
Hence ¬A(b) could be true and the given statement is invalid
b)
Lets Consider G: girl scout
C: selling 50 boxes of cookies
P: getting prize
s: Suzy
Now every girl scout who sells at least 50 boxes of cookies will get a prize: ∀x ∈ G, C(x) -> P(x)
Suzy, a girl scout, got a prize: s ∈ G, P(s)
since P(s) is true, C(s) need not be true
Main Reason: false → true is also true
Therefore the Statement is Invalid
False although depends on the future of the person's ideas
