marble is drawn. Find the
probability.
P(red, red) =

P(red, blue) =

P (red or blue, white) =

Plz help me it would mean a lot!☺

Answer 1

1/2 for red

2/3

b+w=1/2

r+w=5/6

Explanation:

Answer 2

• 1/4; 1/12; 2/9

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
