Q. If a set is defined by the constraints of being a vowel and a letter in the English alphabet, which of the following is an example of an element in this set?
A.
B
B.
C
C.
A
D.
D
Solution
A is a vowel and meets the constraints of being a letter in the English alphabet.
Q. In a constraint-based set of colors, if red and blue are included, which of the following colors could be excluded based on the constraint of primary colors?
A.
Green
B.
Yellow
C.
Purple
D.
Orange
Solution
Purple is a secondary color formed by mixing red and blue, thus it could be excluded if only primary colors are considered.
Q. In a constraint-based set, if the constraints are 'x is a positive integer and x is less than 10', which of the following is the largest element in the set?
A.
8
B.
9
C.
10
D.
7
Solution
The largest element in the set defined by the constraints is '9', as it is the largest positive integer less than 10.
Q. In a constraint-based set, if the constraints are modified to include only even numbers, which of the following would be the new set if the original set was {1, 2, 3, 4, 5, 6}?
A.
{2, 4, 6}
B.
{1, 3, 5}
C.
{1, 2, 3, 4, 5}
D.
{2, 3, 4, 5, 6}
Solution
The new set would be {2, 4, 6} as it includes only the even numbers from the original set.
Q. In a scenario where a set is defined as {x | x is a positive integer and x is less than 10}, which of the following is the largest element in this set?
A.
8
B.
9
C.
10
D.
7
Solution
The largest element in the set of positive integers less than 10 is '9'.
