Now the problem says here three pair of identical twins.
00:14
Half of twins are male and half are female.
00:18
They have purchased eight seats in a row for a concert.
00:30
In how many different ways can they have seated? the first question is given here.
00:37
No restriction, there is no restriction.
00:42
So total number of the ways, if there is no restriction, then total number of ways, that is equal to 8.
00:57
Now, but here we have three identical pairs.
01:02
So the total number of the ways, so this is of 8 factorial, total number of the ways.
01:08
Three twins are there then the total number of ways that is equal to 8 factorial divided by twins are there so 2 factorial 2 factorial multiplied with 1 factorial so after this calculation we get 40320 divided by of 4...
