The table given below shows the month of birth of 36 students of a class:
Month of birth | Jan. | Feb. | March | April | May | June | July | Aug. | Sep. | Oct. | Nov. | Dec. |
No. of students | 4 | 3 | 5 | 0 | 1 | 6 | 1 | 3 | 4 | 3 | 4 | 2 |
A students is chosen at random from the class. What is the probability that the chosen student was born in October?
Total number of students: 36
Number of students born in October: 3
Probability P() = 
Let p(Oct.) be probability of students born in October.
