Suppose that probability that a randomly selected IRSC students is at least 19 years old is 0.55. Round solutions to three decimal places, if necessary. What is the probability that a randomly selected IRSC student is less than 19 years old? P(the student is less than 19 years old) = Suppose two IRSC students are selected at random and calculate the following probabilities. P(Both students are at least 19 years old) = P(Both students are less than 19 years old) = P(the first student is at least 19 years old and the second student is less than 19 years old) =
