This is a binomial probability situation, since a dog either is adopted or is not adopted. The chances of a dog's being adopted in 0.20. Here we're speaking of 9 visits. Thus, n=9, p=0.20.
One way of doing this problem is to calculate the probability that ONE dog will be adopted, and then that that TWO dogs will be adopted, and so on, up to NINE dogs. Add together these nine probabilities to get your answer.
But a better (faster) approach would be to calculate the probability that ZERO dogs will be adopted, and then to subtract this from 1.000.
Using my TI-84Plus calculator, I figured that P(0 dogs will be adopted) is binompdf(9,0.20,0), or 0.134. Subtracting this from 1.000, we get 0.866 (answer to this problem).
Let us assume the length of the rectangle = x
Width of the rectangular dog run = 888 feet
Area of the rectangular dog run = 208 square feet
We already know
Area = Length * Width
Length = Area/Width
= 208/888 feet
= 0.23 feet
So the length of the rectangular dog run is 0.23 feet.
Since you have commented that
you made a mistake in giving the question so the answer will also definitely
change but the procedure will remain the same.
Answer & explantation
Determine a single event with a single outcome.
Identify the total number of outcomes that can occur.
Divide the number of events by the number of possible outcomes.

beginning summer semester and attending an in-state college
174/2=87 or 174/4=43.5
13% probability! or 6-7% probability!
------------------------------------------------------
beginning summer semester and not attending an out-state college
21/2=10.5 or 21/4=5.25
1.5% probability! or 0.75% probability!

wont begin summer semester and attending an in-state college
301/2=150.5 or 301/4=75.25
25% probability! or 12%!

01.655=0.25%
12 gallons = 45.425 liters. (You can divide 45.425 and 12 to get how many gallons are in one liter.) If one liter = 26.9 cents, then we would multiply 45.425 by 26.9. This equals 1,221.9325 cents. That would be about 12 dollars and 22 cents.
Answer:
If the circumference of the shield is 100.48 inches, its radius is 16 inches and the area of the front of the shield is about 803.84 square inches.
Explanation:
Circumference = 2x r x Pi implies r =Circumference / 2Pi=100.48/2x3.14=16
Area = Pi x r²=3.14 x 16²=804.84
