The single urogenital opening in birds and monotremes is called the cloaca.

The random variable X represents the number of classes a student skipped. The probability 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.
