Answer: The required probability is 
Step-by-step explanation: Given that an urn contains 6 red marbles and 4 black marbles. Two marbles are randomly drawn one by one from the urn without replacement.
We are to find the probability that both drawn marbles are black.
Let E and F denote the events of two marbles one by one without replacement and let S and S' denote the corresponding sample spaces.
Then, we have
Therefore, the probability that both marbles are red is given by
Thus, the required probability is
Answer:
Step-by-step explanation:
Let
l------> the length of the base of the prism
w------> the width of the base of the prism
h------> the height of the prism
we know that
The volume of the prism is equal to
Solve for w
That means-------> isolate the variable w
so
Divide both sides by (lh)
Simplify
Answer
B
if you plug in 10 for the Y, you’ll figure that you must subtract 10 from both sides. the. you divide by 2 which makes it an automatic 0.
If you take 3 inches off each end, that means you will be taking 6 inches off. If you take 6 inches away from 7 1/4 yards ,(7 yards, 9 inches,) you get 7 1/12 yards (7 yards, 3 inches).
(7 1/12) / 5 = 1.426repeating
So each piece of rope will be (Approximately) 1.4 or 1 2/5 yards.

<h3>Answer:</h3>
Mean: 17.2
Median: 18
Mode: 18
<h3>Solution:</h3>
Mean: The sum of all observation divided by several observation
- 20+18+13+17+18=86
- 86÷5=
- 17.2
Median:it is the middlemost observation of data arraged in increasing or decreasing order of values
- (13,17,18,18,20)
- (17,18,18)
- (18)
Mode:it is the value that occurs frequently in a set of data
Hope it helps
