If all 25 questions are different,
When order of selection counts:
P(25,7)
=25!/(25-7)!
=15511210043330985984000000/6402373705728000
=2422728000
When order of selection does not count count:
C(25,7)
=25!/(7!*(25-7)!)
=15511210043330985984000000/(6402373705728000*5040)
=480700

Answer:
P(-2,8) Q(-8,8) R(-8,2) S(-2,2)
Step-by-step explanation: 180 degree rotation rule = (x,y) ---- (-x,-y)
ex : point B (-2, 7) will be B' (2, -7)
