In , you were asked to prepare a frequency distribution table regarding 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.

In sum you were asked to prepare a frequency distribution table regarding 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.

In Q.1, Exercise 14.2, you were asked to prepare a frequency distribution table regarding 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.

In Q.1,Exercise 14.2, you were asked to prepare a frequency distribution table regarding 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.

The blood groups of 30 students of Class VIII are recorded as follows:Use this table to determine the probability that a student of this class, selected at random, has blood group AB.

Let us now consider the following frequency distribution table which gives the weights of 38 students of a class:

Consider the following frequency distribution table representing the weights of 40 students of a class . Draw a histogram to represent the above data.

The following table shows the blood groups of 40 students of a class. One student of the class is chosen at random . What is the probability that the chosen student has blood group (i) O ? (ii) AB ?
