Question

Какова вероятность того,что при подбрасывании монеты орел впервые выпадает на четвертом броске?

Answer 1

Исходов всего - восемь ( орел или решка - бросаем 4 раза), благоприятный исход - один из всех восьми, делим 1 на 8 и получаем 0,125%

Answer 2

Probability of Getting Heads on the Fourth Flip

The probability of getting heads on the fourth flip when tossing a fair coin can be calculated using the concept of independent events and the probability of a single event.

Probability Calculation: The probability of getting heads on the fourth flip can be calculated using the formula: \[ P = \frac{m}{n} \] Where: - \( P \) is the probability - \( m \) is the number of successful outcomes (in this case, getting heads on the fourth flip) - \( n \) is the total number of possible outcomes (in this case, the total number of flips)

The probability of getting heads on the fourth flip is \( \frac{1}{2} \) since each flip of a fair coin is an independent event, and the probability of getting heads or tails on each flip is \( \frac{1}{2} \).

Therefore, the probability of getting heads on the fourth flip is 50% according to the concept of independent events and the fairness of the coin.

Conclusion

The probability of getting heads on the fourth flip when tossing a fair coin is 50%.
