20 total marbles....7 are green
probability on first draw is 7/20...and since the marble was not replaced, the probability on the second draw is 6/19. And since they cant happen at the same time, we multiply
7/20 * 6/19 = 42/380 which reduces to 21/190
Answer:
1. A point you can't move at all, a line you can only move back and forth in the same direction. Yes it is accurate for its characteristics because points and lines have no set definition for them
2. When you are on a point you can not travel at all in any direction while staying on that point. That means you have zero options to travel in. That is why it is said you have zero dimensions.
3. Normal space refers 3 dimensional space that extends beyond the three dimensions of length, width, and height.
4. If you can move backward, forwards, up and down in two different directions it is considered two dimensional. The two dimensional figure is considered a plane. For example, if you took a piece of paper that extended forever in every direction, that in a geometric a sense, is a plane. The piece of paper itself is itself, finite, and you could call the piece of paper a plane segment because it is a segment of an entire plane.

Answer:
th part of the bottle will be drunk by the calf.
Step-by-step explanation:
Part of the bottle fed by the piglet = 
Milk left in the bottle = 1 -
= 
= 
Milk drunk by the calf =
th of the left part
= 
=
