96 DESCRIPTION OF THE ACTIVITY Toss a coin and take notes on the results. Toss the coin ten times and write down how many tails and heads (the sides of the coin) you get. Make a throw-in series and record the results two more times ten sets. For example, what is the probability that tossing a coin will give you a head three times in a row? 1/8, as the possible sequences of throw results are (0, 0, 0), (0, 0, 1), (0, 1, 1), (0, 1, 0), (1, 0, 1), (1, 0, 0), (1, 1, 0) and (1, 1, 1). And what is the probability that if you already have two heads, the next roll will also be a head? 1/2, because the coin doesn’t know what you’ve thrown before. Each new throw is unique. Why does not the result you throw yourself seldom match the probability? Try to see if the result starts to approach 50/50 if you toss a coin a hundred times. Think about how much practice would be needed to make the coin spin as you wish and consider the role of chance in coin tossing. TASKS Toss coin. Take notes to prove the laws of probability. GOAL OF TASKS Understand and test the basic concept of probability.
