Discrete or Continuous: 4 Random Variables

Click For Summary
SUMMARY

The discussion categorizes four random variables as either discrete or continuous. The number of people in India (A) is classified as a discrete random variable due to its countable nature. The time it takes to overhaul an engine (B) and the blood pressures of patients admitted to a hospital in one day (C) are classified as continuous random variables, as they can take any value within a range. The length of a centipede (D) is also a continuous random variable, as it can vary continuously.

PREREQUISITES
  • Understanding of discrete random variables

A discrete random variable is one that can take values from a discrete set (one where each value is some how separated from its neighbours).

A continuous random variable is one that can take any value in some interval of the real line.

So what do you think for A,B,C and D
