got the boxes and bubble wrap from four different suppliers, each of the suppliers represent 25% of your
supply. Some of the boxes and bubble wrap you received are poor in quality and not meeting the
specification. You would like to investigate which suppliers that supply good items and which are not.
Based on the table below, generate randomly value Al to A4 and B1 to B4 from 0 to 1 in decimal form.
Then, based on the values generated, determine what is the value of A’l to A'4 and B’1 to B'4.
