Assume that orders are randomly selected from those included in the table Drive thru Restaurant o 142 231 273 329 30 Order Accurate 17 33 54 Order Not Accurate If three different orders are selected, find the probability that they are all from restaurant C The probability is (Round to four decimal places as needed)

Answer 1

Total orders from restaurant A = 329+30 = 359

Total orders from restaurant B = 273+54 = 327

Total orders from restaurant C = 231+33 = 264

Total orders from restaurant D = 142+17 = 159

Total orders = 359+327+264+159 = 1109

If three orders are selected, probability that all three are from restaurant C

= (264/1109)*(263/1108)*(262/1107)

= 0.0134
