Answer: 1/18
Step-by-step explanation:
9 total marbles
2 red
so the first time he picks it would be a 2/9 chance of the marble being red
the second time there would be 8 total marbles and 2 red, so it would be a 2/8 or 1/4 chance.
the probability is found by doing 2/9*1/4 which equals 2/36 or 1/18.

<span>In Babylonia, tunnels were used extensively for irrigation; and a brick-lined pedestrian passage some 3,000 feet (900 meters) long was built about 2180 to 2160 BC under the Euphrates River to connect the royal palace with the temple. Hopefully this answer helps

Hello!

The volume of the square pyramid is approximately 
____________________________________________________________

V = 

First, we must find the area of the square base.
A = l * w
A = 3.5 * 3.5
A = 12.25 km^2
The area of the base is 12.25 km^2. Now, multiply the base area by the perpendicular height. Then divide by 3.
V = (12.25 * 4.7) / 3
V = 19.1916666667
V ≈ 19.19 km^3
