2. Which of the following are logically equivalent to the statement "Some
luminous otters do not wear eyepatches."
if U is the set of all otters, p(x) is the statement "x is luminous", q(x) is the statement "x
wears an eyepatch", L is the set of all luminous otters, and P is the set of all otters who
wear an eyepatch? (Choose all that apply):
I. LN P° 6= Ø
II. L°NP6= Ø
III. Not all luminous otters wear an eyepatch.
IV. Some otters who wear an eyepatch are not luminous.
V. (x EU) (-(p(x) – q(x)))
VI. (3x E U) (p(x) 1x))
