Q. ZZ is the number of wheels on a randomly chosen vehicle.\newlineIs the random variable ZZ discrete or continuous?\newlineChoices:\newline(A)discrete\newline(B)continuous
  1. Discrete Random Variables: Discrete random variables can only take on a countable number of values. Vehicles can only have a whole number of wheels, like 22, 44, 1818, etc.
  2. Continuous Random Variables: Continuous random variables can take on any value within a range, including fractions and decimals. Since you can't have a fraction of a wheel on a vehicle, ZZ can't be continuous.
  3. Conclusion: Therefore, since ZZ can only be a whole number and there's a countable set of possible values, ZZ is a discrete random variable.
