## Spaghetti graph activity

Posted: January 13, 2014 in Uncategorized

On friday we did an activity  of making graph figures with vertex of the least amount of colors.

On my opinion graph coloring helps a lot to difference the diferent vertex of the graph. ## Day 5 Stanford Honor Academy

What we did today:

– We did a hexaflexagon.

– We learnt more of  programing.

–  We learnt the tree.

– We did figures whith polygons.

– We did 2D and 3D shapes with sppaggetis ( I dont know how to write it).

– And lot more of interesting and fun staff.

## What have we learnt 2

Posted: January 10, 2014 in Uncategorized
• What is a pixel? How does it work? Why do we use it? is a physical point in a raster image, we use them as a sample of an original image.
• What is a compound probability? What is the equation? A mathematical term relating to the likeliness of two independent events occurring. P(A+B)= P(A) +P(B).
• Give an example of a mutually exclusive compound probability. You have a dice and you are asked to find the probability of rolling a 1 or a 2. You know when you roll the dice, only one of those numbers can appear, not both. Therefore, these events are mutually exclusive of each other.
• What does mutually exclusive mean? How is it different? Give an example of one that is and one that is not. Two events are mutually exclusive if they cannot occur at the same time. It is different because the two events can not ocurr at the same time. An example is tossing a coin once, which can result in either heads or tails, but not both. Throwing a dice and having a probability of getting a 1 or a 2.
• What is a Venn Diagram? is a diagram that shows all possible logical relations between a finite collection of sets.
• What is a Hexaflexagon? Hexaflexagons are paper hexagons folded from strips of paper which reveal different faces as they are flexed. The Hexaflexagon described here has six different faces.

Today we did and learn:

– I learnt more of programing.

– We did an activity of making 3D shapes.

– We learnt what a hexaflexagon is.

–  And lot more of interesting things. ## What have we learnt

Examples:

– Permutation whith repetition: passcode.

– Permutation whithout repetition: rainbow.

– Combination with repetition: ice cream scoops.

– Combination whithout repetition: student groups.

– Independent probability: coin toss

– Dependent probability: in a box there are 3 blue balls and 2 red balls. after you take one ball you dont put it again in the box.What is the probability of getting a blue ball? What is the probabillity of getting a blue ball again?

– Why is the prisoners dilemma a dilemma?  because you dont know what your friend is going to choose.

– What is a dominant strategy? it is the best strategy you can use in prisoners dilemma.

– What is a nash equilibrium? both players use the dominant strategy.

–  What is a simultaneous game?  when the 2 players choose an option whithout knowing the chose of the other player.

-What is the Monty Hall problem? its a game where there are 3 doors, 2 of them have a goat and one of tem has a car,then you need to choose a door, the host opens a door whith a goat and you have the option of changing of door. After that you open the door you chose.

-What is information cascade? when you have an answer but the rest of the group has another so you change to their answer. ## Day 3 Stanford Honor Academy

The best thing of today was learning to program animations. But we also  did a lot more of things:

– Building a nyan cat whit squares.

-Exercices of probabilities.

– An lot more of interesting and fun things
