Question

Express these statement using predicates and quantifiers.

A student must take at least 60 course hours ,or atleast 45 course hours and write a master’s thesis, and receive a grade no lower than a B in all required courses, to receive a master’s degree.

Answer 1

$N(x,n)$ = True if number of course hours by student x is greater than n

$M(x)$ = True if master's thesis is written by student $x$

$G(x,y,c)$ = Grade scored by student $x$ in course $y$ is atleast $c$

For a student $x$ to receive degree = $N(x,60)\,\vee\, (N(x,45)\, \wedge\,M(x)\,\wedge\,\forall y(G(x,y,B)))$

Comments

Answer is given as

,I am not getting the correct way how to solve this

It's the same just the meaning of predicates

H(x) returns True if the student M have hours greater than x, 'T' returns True if he have  a masters degree and G(B,y) returns True if he has a grade B or greater in Course y.

I will update the answer
