So I need help finding the data inputs for AB, I understand how to find the Relative frequency and Angle Allotted. However, I can't find either for AB because there no data to go from. What should I do?

2) (5 + 5 + 5 points) Complete the following table on the data of 200 patients in a hospital about their blood groups and draw the Pie chart and bar graph based on this table. Blood Group Frequency Rel.Frequency Angle Allotted A 60 0.3 0.3 X 360 = 108 B 70 AB O 45 Total 360
