Three instructors, Ms. Busby, Mr. Butler, and Mrs. Hutchison, assign projects in their precalculus classes. Some students use graphing calculators with their project, and some de not. The following table summarizes the number of students in each type of project: Busby Butler Hutchinson Total Calculator 14 10 19 43 No Calculator 13 18 10 41 Total 27 28 29 84 (a) Form a related table with entries that are relative frequencies. (Round your answers to three decimal places.) Busby Butler Hutchinson Calculator No Calculator (b) Based on the relative frequencies, estimate the probability that a student selected at random uses a graphing calculator.
