[amp_mcq option1=”Variables” option2=”Literals” option3=”Discrete variable” option4=”Possible states of the world” correct=”option3″]
The correct answer is C. Discrete variable.
A discrete variable is a variable that can take on only a finite number of values. For example, the number of children in a family is a discrete variable, because it can only take on values such as 0, 1, 2, 3, and so on.
A variable is a quantity that can change. For example, the temperature of a room is a variable, because it can change from one moment to the next.
A literal is a symbol that represents a value. For example, the number 5 is a literal.
Possible states of the world are all the possible ways that the world could be. For example, the possible states of the world for a coin toss are heads and tails.
I hope this helps!
