This math topic focuses on calculating probabilities for discrete random variables by utilizing probability tables. The exercises require calculating the probability that the random variable \( X \) falls within specific ranges, using given probabilities for individual values of \( X \). Students analyze various scenarios to sum the appropriate probabilities to answer questions about the likelihood of \( X \) being between, less than, or equal to certain values. This skill is fundamental in understanding the behavior of random variables within the broader field of elementary probability and statistics.
