From the following table which shows marks obtained by $50$ students in a maths class test, draw a bar graph.

Marks	$4$	$5$	$6$	$7$	$8$	$9$	$10$
Number of students	$3$	$5$	$8$	$12$	$10$	$9$	$3$

 

 Draw a bar graph to represent the following information. 

Draw a bar graph to represent the following information.

In which case, the chance of desired outcome is more?

Case I: Getting $\mathrm{H}$ in a toss of a coin.

Case II: Getting $4$ in a throw of die.

Consider the following two situations:

Situation $1$: Chance of getting $2$ or $5$ in a throw of die.

Situation $2$: Chance of getting $1,3$ or $5$ in a throw of die.

Which situation has more chance to occur?

The table given below is the distribution of marks of $40$ students in a class.

The class-size of the given distribution is
