Dear Sir, Please refer to your video lecture on probability. In the last video on JEE questions, there is one question : Out of {1,2.3.4.5.6} two nos. are selected, what is the probability that minimum of the number is less than 4. You have calculated the favourable outcome as 6x4= 24 and total sample space as 6x5= 30. Therefore, the probability is calculated as 24/30= 4/5. though the answer is correct, I am not able to follow how the favourable outcome is calculated as 6x4. Please clarify and review your solution

							Favorable outcome can be calculated as: Let one number be 1 then in combination with it there can be 5 possibilities(2,3,4,5,6) +Let one number be 2 then in combination with it there can be 5 possibilities(1,3,4,5,6)+Let one number be 3 then in combination with it there can be 5 possibilities(1,2,4,5,6)+Let one number be 4 then in combination with it there can be 3 possibilities (1,2,3) +Let one number be 5 then in combination with it there can be 3 possibilities (1,2,3) +Let one number be 6 then in combination with it there can be 3 possibilities (1,2,3). Therefore, in total there can be 24 favorable outcomes.
