International Baccalaureate Math Studies: P&S HELP

[Ti-Pro.doc.]

Could someone help me with this problem:

Two marbles are drawn in succession from a box containing 2 Purple marbles and 5 Green marbles.
Determine the probability that the two marbles are different colors if:

• The first marble is replaced [/*:m:uyr8wajw]
• The first marble is NOT replaced.[/*:m:uyr8wajw]

Could you show me how to represent this on a Tree Diagram.

Thx in advance.

Hello, Ti-Pro.doc.!

Two marbles are drawn in succession from a box
. . containing: 2 Purple marbles and 5 Green marbles.
Determine the probability that the two marbles are different colors if:

The first marble is replaced.

. . . \(\displaystyle \begin{array}{ccccccc}& & & * \\ & & \frac{2}{7}\swarrow & & \searrow\frac{5}{7} \\ & P & & & & G \\ & \frac{2}{7}\swarrow\searrow\frac{5}{7} & & & & \frac{2}{7}\swarrow\searrow\frac{5}{7} \\ P && G && P && G \end{array}\)

The first marble is NOT replaced.

. . . \(\displaystyle \begin{array}{ccccccc}& & & * \\ & & \frac{2}{7}\swarrow & & \searrow\frac{5}{7} \\ & P & & & & G \\ & \frac{1}{6}\swarrow\searrow\frac{5}{6} & & & & \frac{2}{6}\swarrow\searrow\frac{5}{6} \\ P && G && P && G \end{array}\)
