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.

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 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.

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.

Today we learnt and did:

-We learnt to program

– We learnt independent an dependent probabilities

-We did mathematical games

-We did a pre-test
