Ajar contains 3 red, 4 blue, and 5 white marbles. what is the probability of drawing first a red and then, without replacement, a white marble?

5/44

Step-by-step explanation:

You start with a 3/12 probability of getting red and then once there are only 11 marbles left you have a 5/11 chance of getting a white marble.

3/12 x 5/11 = 15/126 reducable to 5/44

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
