I am on a holiday in Dolbania. Five different denominations of coin are in circulation here. I know they are worth five cents $.10 $.25 $.50 and one dollar. But I don’t know which is which and the values are not marked on them one of the coins has a star on it one has a tree one has a cat one has a bird and one has a fish. I visit the same café every morning. Normally I buy a cup of coffee and a slice of carrot cake. The cost is $3.20 and I pay with a five dollar note on the first morning I received three fish coins and three cat coins as change. On the second morning my change was five fish coins five bird coins and one star coin. A) what is the value of the “cat” coin? B) Today I ordered the usual cup of coffee but instead with two slices on carrot cake, I paid in five dollar note once again and my change was a single cat coin. How much does the cup of coffee cost?

You will simulate shooting basketball free throws. Using any coin, let heads represent the ball going into the basket and tales represent the ball missing the basket. Each toss of the coin represents a shot at the free throw line. Simulate shooting 35 free throws. Make a chart on your paper similar to the one below to record your results. For each trial (toss), place an x in the appropriate column. Toss number 1 2 Went in (Heads) X Questions: 1. How many free throws went into the basket? 2. How many free throws missed the basket? Missed (Tails) X 3. What is the experimental probability that you will make the next free throw? 4. What is the experimental probability that you will miss the next free throw? 5. This simulation assumes that you have an equal chance of making the free throw or missing the free throw. Is this a correct assumption? Why? 6. How would you change this simulation to better predict a person's abilities at making free throws?
