Could yu pleas help with the answer to D with clear explanations

[drnand]

2:27 Is wrong.

It is _ B _ B_ B_B_

Girls can sit any 3 Blanks since it's in a row.

If it was a circle u are right

[arinzeanthony]

My answer for D is (case a)-(case c) = 5040-1440
= 3600 ways.
Is that correct?

[saipatil]

Bro in question a) there is also the position for girls at the end like :-
G B G B G B G B G
Even thought, girls are 3 but the position are 5 for alternation. Isn't it possible?
Just the query.

[justinekurltrio]

d) total po nila minus sa answer sa letter c.
7!-6!×2!

[bohemian_]

Find the number of ways in which 4 boys and 4 girls are sitting alternately if one boy and one girl are to sit in adjacent seats. (Ans. 504 ways)

Ano pong solution nito?

[jamessantos]

Mali yung A kasi pwedering ring mauna yung girls kesa boy so multiply pa sya sa 2
