The percentage of marks obtained, in different subjects by Ashok Sharma (in an examination) are given below. Draw a bar graph to represent it.

The marks obtained by 100 students in a Mathematics test are given below : Draw an ogive for the given distribution on a graph sheet. (Use a scale of 2 cm = 10 units on both axis). Use the ogive to estimate the number of students who obtained more than 85% marks in the test.

The marks obtained by 120 styudents in a test are given below : Draw an ogive for the given distribution on a graph sheet Use suitable scale for ogive to estiamte the following : (i) The number of students who obtained more than 75% marks in the test.

In a single throw of a die, find the probability of getting a number : (i) greater than 2 (ii) less than or equal to 2 (iii) not greater than 2.

The marks obtained (out of 100) by 400 students in an examination are given below: Using a graph paper, draw an ogive for the above distribution. Use ogive to estimate the following: estimate the number of students who obtained more than 80% marks in the examination.
