Horatio Oscar Vineeth Lane (HOV Lane for short) records his commute times for a period of one month and assigned them to five different categories as shown in the table.

Commute Length	Number of Observations
commute time <10 minutes	1
10 ≤ commute time < 20 minutes	2
20 ≤ commute time < 30 minutes	4
30 ≤ commute time < 40 minutes	9
40 ≤ commute time < 50 minutes	4

What is the probability that Mr. Lane makes it home in under thirty minutes?
