A red-line drawings is essentially an intermediate drawing that shows corrections or changes to a previous drawing. The term red line literally comes from the (typically) red pen used to amend the drawings by hand. These changes mark-ups show changes made to the drawing subject matter during the manufactuer or construction of the product.
For example, piping drawings were developed at the onset of a project to build a new school. During the course of construction for that school, the piping contractors changes several elements of the design (pipe size, routing, orientation etc). At the end of the project, the constructor would "red line" the drawings showing those changes.
Red-lines are used to then develop record drawings. Record drawings, also called "as-builts" accurately reflect what was constructed and are used for future work and/or reference.
Since 1/2 of the cards are red, the probability of drawing a red card is 1/2 or 0.5.
4 out of 25
The probability of drawing a red two from a standard deck of 52 cards is 2 in 52, or about 0.03846.
The probability of drawing a red heart is 1 in 4. This is the same as the probability of drawing a heart, as red is included as a superset of hearts.

Red, definitiely Red
The probability of drawing a red card is 1/2 (26/52).The probability of drawing a face card is 3/13 (12/52).The probability of drawing a red face card is 3/26 (6/52).The probability of drawing a red card or a face card is 8/13 (32/52).2 out of 52or 1 out of 26.
The answer is dependent on whether of not you replace the marbles in the jar. If you do, the probability of drawing a red marble is 9 in 15 or 60%, every time. If you do not replace the marbles, the probability of drawing a red marble is 2 in 8 or 25%.
