Q. ZZ is the number of desserts available in a randomly chosen restaurant.\newlineIs the random variable ZZ discrete or continuous?\newlineChoices:\newline(A) discrete\newline(B) continuous
  1. Whole Number Desserts: The number of desserts can only be whole numbers; you can't have half a dessert on the menu. So, ZZ is a count of items.
  2. Distinct Values for ZZ: Since ZZ counts whole items, it's not something that can take on any value in an interval. It's not like measuring something where you can have fractions or decimals.
  3. Z is Discrete: So, ZZ is a type of random variable that takes on separate, distinct values. That's what discrete means, so ZZ is discrete.
