Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Common mistake, if you choose any two objects, the others are also CHOSEN so since you are choosing twice, the order of choice matters
You choose once,technically you dont need to choose again
I didn't quite get it
i told you to choose between 1,2,3,4
you picked 1,2
thats different
you picked 3,4 thats different
Right
i told you to seperate 1,2,3,4 into two groups
you first chose 1,2
thats one way
but choosing 3,4 is also the same right
Yeah right
Lemme read this again
im leaving this q to see and test yourself if you understand, suppose i wanted to split 1,2,3,4,5,6 into 3 groups of size 2, the answer should 6c2 times 4c2/3!
Why did divide by 3! Here
Cause geouping
Grouping
because you are choosing in a order
see consider the case (1,2)(3,4)(5,6)
Accha accha
that is counted once when (1,2)(3,4)(5,6) is made in that order, or (1,2)(5,6)(3,4) etc
Yeah that i got it won't matter which I pick first
yes
Right
In the question each clothing has 2 colours in common
you just need to split the colour into 2 groups of 2
The ways to pick pairs with same colors is only 3
That seems so less
Okay okay
try to understand this one, if you got it you should get it
ok bye
Alright I'll get back to you thank you
They said to pick of the same color, but which color doesn't matter right
if shirts and skirts are chosen for same colour , u wont have to choose scarves and hats again for diff colour. they are automatically chosen.
I think I understood you guys
