|Blood Group||Number of Students|
The above frequency distribution table represents the blood groups of 30 students of a class. Use this table to determine the probability that a student of this class, selected at random, has blood group AB.
Number of students having blood group AB = 3
Total number of students = 30
Hence, required probability, `P = 3/30 = 1/10`
