Compute a frequency distribution or tally showing how many are in each room.  Then Calculate the percent in each room:
 

Room	Frequency	Percent
101	.	.
105	.	.
106	.	.
108	.	.
109	.	.
120	.	.
123	.	.
124	.	.
218	.	.
TOTAL	.	.

Now draw a histogram of this frequency distribution similar to the one pictured.
