Краткое пояснение: Вероятность события равна отношению числа благоприятных исходов к общему числу исходов.
- 1. N = 24, N(A) = 6. P(A) = N(A) / N = 6 / 24 = 1 / 4 = 0.25
- 2. N = 50, N(A) = 15. P(A) = N(A) / N = 15 / 50 = 3 / 10 = 0.3
- 3. N = 40, N(A) = 28. P(A) = N(A) / N = 28 / 40 = 7 / 10 = 0.7
- 4. N = 20, N(A) = 4. P(A) = N(A) / N = 4 / 20 = 1 / 5 = 0.2
- 5. N = 18, N(A) = 9. P(A) = N(A) / N = 9 / 18 = 1 / 2 = 0.5
- 6. N = 15, N(A) = 12. P(A) = N(A) / N = 12 / 15 = 4 / 5 = 0.8
