Which one of the following alternatives is FALSE regarding the number
sets Z, Z , Z , Q and R? a. Z ⊆ Z b. Z ⊆ Z c. R ⊆ Q d. Z ⊆ R + ≥ ≥ + ≥ +
Let's break down each option:

a. Z ⊆ Z: This statement is true since the set of integers (Z) is a subset of
itself.

b. Z ⊆ Z: This statement is also true for the same reason as option (a).

c. R ⊆ Q: This statement is false. R represents the set of real numbers,
which includes both rational (Q) and irrational numbers. Therefore, R is
not a subset of Q.

d. Z ⊆ R+: This statement is true. Z represents the set of integers, and R+
represents the set of positive real numbers. Every integer is also a real
number, and every positive integer is a positive real number, so Z is
indeed a subset of R+.

So, the FALSE statement is c. R ⊆ Q.




The set of all non-negative integers x less than 16 such that x is an even
integer can be described as the set: (Note: The required set must include
