Is PNC tough?
Probability is just a subset of this. P & C has the calibre to become a nightmare in the life of a JEE aspirant. I had a tough time dealing with it. A lot of extra effort was required compared to most other topics of mathematics.
What is the formula for permutations step by step?
For example, 7! = 7 * 6 * 5 * 4 * 3 * 2 * 1 = 5,040. To calculate permutations, we use the equation nPr, where n is the total number of choices and r is the amount of items being selected. To solve this equation, use the equation nPr = n! / (n - r)!.
Permutation and combination are different ways to represent the group of objects by rearranging them and without replacement, to show their subsets.
