In mathematics, permutations refer to the arrangement of objects in a specific order. A permutation of a set is an ordered arrangement of its elements. For example, if you have a set {A, B, C}, there are six possible permutations:
1. ABC
2. ACB
3. BAC
4. BCA
5. CAB
6. CBA
In general, if you have a set of n distinct elements, there are n! (n factorial) permutations. The factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. Mathematically, it is expressed as:
n! = n × (n-1) × (n-2) × ... × 3 × 2 × 1
For example, 5! = 5 × 4 × 3 × 2 × 1 = 120.
Permutations are often used in combinatorics, a branch of mathematics dealing with counting, arrangement, and combination of objects. They have applications in various areas such as probability, statistics, and cryptography.

Thank you very much sir

[@IbrahimKalil-oi2eg]

I don't understand the way he does the first question. I suppose the formation of 3 digit even number from 1-6 would be 3*3*3=27

[@KalidEngdawork]

Yeah me too

[@KalidEngdawork]

I also felt the same but I asked a friend of mine and he told me thar when it says " 3 digit even number " it's about the whole number rather than the individual numbers like, 796 is an even number because 6 is even despite the fact 7,9 are odd so the answer becomes 6×6×3 =108 ❤🎉

[@sowjanyachinagudaba4527]

Sir please make all class 11th topics videos

[@Silenced_YT]

[@titanicgamer1174]

[@AlindaCleverson-cm7sg]

Am getting 96 as the answer ✍️

[@TejasNaidu-er6kn]

The black shirt and cream pants

[@akshajaniket2538]

A question is wrong @57:39 as the number of digits in thousand place is 8 because 0 can not come in the first place ,so the answer is 8*9*8*7

[@nethmimanusha5486]

Nope, I think it's right.... Because there are 10 numbers in 0-9 range....

[@akshajaniket2538]

Look carefully

[@bhanumathikrishnamurthy7193]
