Discrete Random Variable
A discrete random variable can take only separate, countable values, often whole numbers, with gaps between them. Examples include the number of goals in a match or the score on a die.
Its probabilities are listed individually and must add up to one across all values.

Where it appears in Add Math
You meet Discrete Random Variable in the Probability Distribution chapter of SPM Additional Mathematics. Knowing the term precisely matters in the exam: questions often hinge on reading a keyword correctly, and because SPM marking is analytic, using the right definition in your working helps secure method marks.
Our teachers make sure a student can not only recite what Discrete Random Variable means but use it fluently in a full solution.
The term in three languages
Because the SPM Add Math paper is bilingual (BM/EN), it helps to know this term in each language: Discrete Random Variable (EN) · Pemboleh ubah Rawak Diskret (BM) · 离散随机变量 (中文)
