МатематикаВопрос:
b) Assume, what should be the theoretical frequency of the appearance of heads when tossing a coin? 0.5 Why?
Ответ:
б) Предположите, какая теоретически должна быть частота выпадения орла при бросании монеты? 0,5
Почему? У симметричной монеты шансы на выпадение орла и решки равны.

- Prepared by the student: Date:
- Prepare the coin. To determine how often a coin lands on heads, we will toss the coin and record the number of heads. If heads comes up, draw a tick in the first row, if tails - in the second row. Toss the coin 100 times and fill in Table 1 (use the symbol "|"). Table 1 Side of the coin: Thrown: Heads: Tails: Total:
- 2. Stage. 3. Stage.
- In this experiment, the denominator for all calculations is 100 - the total number of tosses, and substitute the numbers obtained in the experiment into the numerator. Frequency = number of heads / total number of tosses
- a) Fill in the last column of Table 1, determining the frequency of heads falling out using the formula (round all numbers to two decimal places):
- c) Compare your experimentally obtained results with the predicted ones.
- g) How can you find the frequency of tails appearing in this experiment? (Indicate two ways!)
- 3. Stage.
- Discuss the results of the entire class's work.
- a) How many pairs of students got a frequency of exactly 0.5?
- b) How many pairs of students got a frequency greater than 0.5?
- c) How many pairs of students got a frequency less than 0.5?
- g) Compare the number of answers to the two previous questions, b) and c)
