Answer:
The length of the rectangular banner is 10 inches
The width of the rectangular banner is 2 inches .
Step-by-step explanation:
Given as :
The length of rectangular banner is five times as long as its width
The perimeter of rectangular banner = P = 24 inches
Let The width of rectangular banner = w inches
And The length of rectangular banner = 5 w inches
Now, According to question
The perimeter of rectangular banner = perimeter of rectangle = 2 × length + 2 × width
Or, The perimeter of rectangular banner = 2 × 5 w + 2 × w
Or, 24 inches = 10 w + 2 w
Or, 24 inches = 12 w
∴ w =
I.e w = 2 inches
So, The width of rectangular banner = w = 2 inches
Put the value of w to get length
So, The length of rectangular banner = 5 × 2 = 10 inches
Hence The length of the rectangular banner is 10 inches and The width of the rectangular banner is 2 inches . Answer

Answer:
The probability that she gets all the red ones, given that she gets the fluorescent pink one, is P=0.0035 or 0.35%.
Step-by-step explanation:
Susan grabs four marbles at random.
We have to calculate the probabilities that he picks the 3 red ones, given that she already picked the fluorescent pink.
If it is given that the fluorescent pink is already picked, we are left with three red marbles, four green ones, two yellow ones, and four orange ones. A total of 13 marbles.
The probability that the second marble is red is 3 in 13.
The probability that the third marble is also red is 2 (the red marbles that are left) in 12 (the total amount of marbles left), as there is a picking without replacement.
The probability that the fourth marble is 1 in 11.
Then, the probability that the 3 red marbles are picked, is:
