Consider the chance experiment that selects one of the study participants at random and dene the following events. T = event that selected faculty member uses Twitter C = event that selected faculty member sometimes uses Twitter to communicate with students L = event that selected faculty member sometimes uses Twitter as a learning tool in the classroom (a) Two of the percentages given in the problem specify unconditional probabilities, and the other two percentages specify conditional probabilities. Which are conditional probabilities? (Select all that apply.) O 30.8% reported that they use Twitter C] 69.2% said that they did not use Twitter.
