Question: A bag contains 5 black and 6 white balls; two balls are drawn at random. What is the probability that the balls drawn are white?

​​​Solution:
​Given that,
​Number of black balls = 5
​Number of white balls = 6

​Now, 
​Favorable event = 6C2 = 15
​Total possible events = 11C2 = 55

​∴ Probability = 15/55 = 3/11
