An easier version of letter C "Even numbers without repitition". 4 digits greater than 3000 from 1,2,3,4,5,6 1. Count the number of even numbers among 1,2,3,4,5,6 that is greater than 3000. That will be {4,6} or 2 ways so our first number will be 2 ,_ ,_ ,_ 2. Since in the first number we could choose either 4 or 6, that means we still have 5 more numbers to choose for the 2nd as repition is not allowed. if we choose 2, then we still have 6,5,4,3,1 to choose from or 5 ways if we choose 6, then we still have 6,5,3,2,1 to choose from or 5 ways that means our next number is 5. 2,5,_ ,_ (Just continure to use step 2 for the remaining numbers) Then 4 options to choose for the third, and 3 options to choose for the last we now have 2,5,4,3 2,5,4,3 = 120 ways I'm not sure if this is correct but this is how i've done it before.

@mehrosenasir3966

Munda Punjabi , it’s quite easy to get confused with permutation and combination specially when we allow the repetition in permutation. Consider this example, I have to make a fruit salad and I have 3 items; banana,apple and mango. would the order really matter in the condition? Eventually, it will be a fruit salad, it won’t matter which fruit I choose first. Now consider this one let’s say I have to set a password for my phone which is 6789, if i change the order, assume 7689, would my phone get unlocked?. In this example order really matters. Just practice things out, you will get a sense of it
