Suppose a study of speeding violations and drivers who use cell phones produced the following fictional data: Uses cell phone while driving Does not use cell phone while driving Total Table 3.2 Speeding violation in the last year 25 45 70 No speeding violation in the last year 280 405 685 Total a. Find P(Driver is a cell phone user). b. Find P(driver had no violation in the last year). c. Find P(Driver had no violation in the last year AND was a cell phone user). 305 450 755 The total number of people in the sample is 755. The row totals are 305 and 450. The column totals are 70 and 685. Notice that 305 + 450 = 755 and 70 +685 = 755. Calculate the following probabilities using the table.
