Answer:

None.

Step-by-step explanation:

Let blue, green and purple be B, G, and P respectively.

Sample Space = 2+2+2 = 6

p(B) = p(G) = p(P) = 2/6 = 1/3

Probability that the two marbles Ummi selected are of the same color (note that the marbles were replaced after selection)

B = (1/3)•(1/3)

+

G = (1/3)•(1/3)

+

P = (1/3)•(1/3)

= 3•(1/9) = 1/3

.

The same thing goes for Julio.

They have the same chance/probability of picking two marbles of the same color.
