 Hi and welcome to the session. I'm Panika and I'm going to help you to solve the following question. The question says the blood cloves of 30 students of class A are recorded as follows A,B,O,O, A,B,O,A,O,V,A,O,V,A,O,V,A,O,O. A,A,B,O,A,A,O,O, A,B,B,A,O,V,A,V,O. Represent this data in the form of a frequency distribution table which is the most common and which is the rarest blood group among these two legs. Let's now begin with the solution. Frequency distribution table is the method by which we can represent raw data in the form from which one can easily understand the information contained in the raw data. Let's now make a frequency distribution table of the given data. We have made this table with two collabs, one for the blood groups and one for the number of students. Groups A for respective rows. Calculate that how many students has A blood group? 1, 8, 9. So now we will write 9 in this column. Calculate that how many students has B blood group? How many students has O blood group? 9, 10, 11, 12. So write 12 here. Now find that how many students has AB blood group? B blood group. Now from this table we will find that which blood group is the most common O blood group? So this means strong when group is O. Thanks and bye and take care.
