Thanks!

Thanks man

Thanks m8

Thank you, but that is incorrect.

Solution I found: 

We will consider this as a composite of two problems with two indistinguishable balls and 3 distinguishable boxes. For two indistinguishable green balls, we can place the balls in a box together or in separate boxes. There are 3 options to arrange them together (in box 1, 2, or 3) and 3 options for placing them separately (nothing in box 1, 2, or 3). So there are 6 ways to arrange the indistinguishable green balls. By the same reasoning, there are 6 ways to arrange the indistinguishable red balls, for a total of 6*6=36 arrangements of the 4 balls.

thank you guys!

By the way that is incorrect

Real Solution

Since the plants are indistinguishable, we must only count the number of plants on each window sill.

If 5 all the plants are on one window sill, there are  ways to choose which window sill they are on.

If 5 plants are on one window sill and the last is on another, there are  ways to choose which plants go on which window sill.

If 4 plants are on one window sill and the last two are on another, there are  ways to choose which window sill they are on.

If 4 plants are on one window sill and the last two are each on one of the other windows, there are  ways to choose which window the plants are on.

If 3 plants are on one window and the other  plants are all on another window, there are  ways to choose which window has no plants.

If 3 plants are on one window,  plants on another window, and  plant on the last window, there are  ways to choose which plants are on which windows.

If 2 plants are on each window, there is only one way to arrange them.

In total, there are \(3+6+6+3+3+6+1=\boxed{28}\) ways to arrange the plants on the window sills.

 

What is the probability that each of her next five stops is on the 7th floor or higher, You can go down one and go up 4, 

Both are the same answer (:

ANSWER: \(\boxed{100}\)

Thus if s=length of each side of the rhombus, then
\(s²=(AC/2)²+(BD/2)²\)
using Pythagoras theorem. 
Calculate (Multiply S by 4 to get final answer because all four sides are equal)
\(s=√(7²+24²)  =25 \)

Can anyone do this, im really stuck.....
