The rаndоm vаriаble X represents the number оf classes a student skipped. The prоbability distribution for this scenario is shown below. Number of Classes p(x) 0 0.21 1 0.38 2 0.34 3 0.05 4 0.02 The probability that a randomly selected student skipped exactly 4 classes is Event A. The probability that a randomly selected student skipped at most 2 classes is Event B. The probability that a randomly selected student skipped at least 3 classes is Event C. Find the average number of skipped classes for this population.
