Hi;

I have missed your solutions and if you notice I have been training young anonimnystefy and others to follow in our footsteps!

Hi,

Yes, I too miss math. I need to find a way which can give me plenty of time!

I have noticed it, you are doing a good job.

It's nice to get hold of computers and math early.

See you later.

**New Problem:**

**Baffler #222**

**The line y = x + 5 intersects the curve y = x^2 - 2x at points A and B . If we place Point C on the curve ( beneath A and B ) what is the maximum area of triangle ABC we can make? ( see the diagram )**

**A says) 20.**

**B says) That is close, the real answer is (7 +**

**C says) 20 sounds about right to me.**

**D says)C, why do always interrupt B before he can put his answer down? You know he is always wrong.**

**E says) I think he was right, I am getting that too.**

**What is the maximum area that can be attained?**

The more I think about the problem #1 in this thread, the less I believe in the answers given to it in this thread

I do not think we can talk about percentage of white marbles in the jar at all. We can talk only about probabilities.

At the beginning we have 50 blue and 50 white.

On a first step we can remove 25 blue, 25 white or any number of blues and white (up to 25). So after putting 25 blue ones back into the jar we can have either:

50b+50w, or 75b+25w, or some numbers in between.

After repeating this process the second time, numbers can become 50b+50w, or 100b+0w, or some numbers in between.

In other words, after 10 steps we can have 50% marbles in the jar are white, or 0% (possibly even after the second step) or any number between 0 and 50.
