Transcribed Image Text:A report describes results of a survey of nearly 2000 college faculty. The report indicates the following.
• 30.3% reported that they use Twitter and 69.7% said that they did not use Twitter.
• Of those who use Twitter, 39.1% said they sometimes use Twitter to communicate with students.
Of those who use Twitter, 27.5% said that they sometimes use Twitter as a learning tool in the classroom.
Consider the chance experiment that selects one of the study participants at random and define 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

Transcribed Image Text:(c) What proportion of the faculty surveyed sometimes use Twitter to communicate with students? (Hint: Use the law of total probability to find P(C). Round your answer to three decimal places.)
(d) What proportion of faculty surveyed sometimes use Twitter as a learning tool in the classroom? (Round your answer to three decimal places.)
