Question

Помогите пожалуйста!! Очень нужно!! Монету подбросили 100 раз, герб выпал 68 раз. Можно ли считать, что подбрасывали симметричную монету?

Answer 1

У симметричной монеты при таком большом числе бросков должно быть гораздо ближе к 50. Ну, 52 на 48.

Answer 2

Да  мне так кажеться что может

Answer 3

Analysis of Coin Toss Results

Based on the information provided, a coin was tossed 100 times, and the result was 68 heads. The question is whether it can be considered that a fair, symmetric coin was used for the tosses.

Statistical Analysis: The concept of a fair, symmetric coin implies that the probability of getting heads or tails is equal. In this case, the expected number of heads in 100 tosses of a fair coin would be 50.

Probability Calculation: The probability of getting heads in a fair coin toss is 0.5. Therefore, the expected number of heads in 100 tosses can be calculated as: ``` Expected number of heads = Probability of heads * Number of tosses Expected number of heads = 0.5 * 100 = 50 ``` Comparison with Actual Results: Given that the actual number of heads obtained was 68, it is higher than the expected number of 50 for a fair coin.

Conclusion: Based on the results, it is reasonable to question whether the coin used for the tosses is truly fair and symmetric. The higher than expected number of heads suggests a potential bias in the coin.
