Detailed explanation-1: -Discrete data is a numerical type of data that includes whole, concrete numbers with specific and fixed data values determined by counting. Continuous data includes complex numbers and varying data values measured over a particular time interval.
Detailed explanation-2: -A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring. A random variable is a variable whose value is a numerical outcome of a random phenomenon. A discrete random variable X has a countable number of possible values.
Detailed explanation-3: -The weight of a book is something that can be measured, e.g. using a weighing scale. Because of this, the weight of the book falls under the continuous variable. If the variable is something that can be counted, then it is discrete. Therefore, the correct answer is a continuous variable.
