Answer:

1/4; 1/12; 2/9

Step-by-step explanation:

4 white, 2 blue, 6 red marbles

Total number of marbles is:

4 + 2 + 6 = 12

Probabilities are:

P (red, red) = 6/12*6/12 = 1/2*1/2 = 1/4
P (red, blue) = 6/12*2/12 = 1/2*1/6 = 1/12
P (red or blue, white) = (6+2)/12 *4/12 = 8/12*1/3 = 2/3*1/3 = 2/9
