Fun Day in Math

Probability Project

Today you will begin writing the summaries of your probability projects in your blogs. In your summaries, I would like for you to include a few sentences about each of the following:

• Before - What did you do before playing the game? This would be the front of your paper. You will need to talk about theoretical probabilities and predictions here.
  
• During - What happened during the game? You will need to talk about experimental probability here and if it matched your theoretical probability.
• After - Based on your results, is the game fair? How could you change it to make it fair?

Please work with your group to begin writing rough drafts of your summaries. Click on the comment link below to begin writing.

Let's play Monty's Dilemma -- Should you stick or switch?

http://matti.usu.edu/nlvm/nav/category_g_3_t_5.html

Play the game several times (at least 25) and then write a strategy in the comments section below. Please include the data you found.

Roll of the Die

Dados, originally uploaded by A Outra Voz.

In our last short cycle of the year (yeah!), we will be covering probability. The following questions are about the photo above. They will test what you already know about probability.

1) How many possible OUTCOMES are there when tossing a die?

2) What is the THEORETICAL probability of tossing a 1? Write your answer as a fraction.

3) Suppose you toss the die 20 times and a 6 comes up on 3 of those tosses? What is the EXPERIMENTAL probability? Write as a fraction.

4) Suppose you toss the die twice. What is the probability of rolling a 2 both times?

What is the area of this triangle?

Find the area of this triangle. Remember the formula is 1/2 b*h, or b*h/2.

Make sure you write a quick explanation that includes the usual requirements.

Linear Patterns

Linear Patterns, originally uploaded by Misterteacher.

Write an ordered pair for each point and then write an equation for the graph.

Each ordered pair should be written like this: (x,y).

Hint for finding the equation: Set up a t-chart on a sheet of paper and find the rule.

Bonus: Explain how to write an equation by looking at the ordered pairs.

Solving One - Step Equations

Problem 1: Explain how you would solve the following problems. You must use the following words in your explanation: inverse operation, balance, simplify.

(a) 36.7 - y = 18.20 (b) 5x = 45 (c) b/5 = 5

An excellent answer will contain the following qualities:

• Sequence Words - first, next, last, etc.
• Steps in correct order.
• A correct solution.
