Question

В ящике лежат 24 одинаковых карандаша. Из них 13 красные, а остальные -синие. Наудачу достают один карандаш. Найдите вероятность события:"Карандаш не синий ".

Answer 1

13\24 ( Вероятность красных делить на вероятность синих) = 0.541 - вероятность того, что карандаш красный, 1 - 0.541 = 0.459 - вероятность, что карандаш синий

Answer 2

Problem Analysis

In the given problem, there are 24 identical pencils in a box. Out of these, 13 are red and the rest are blue. We need to find the probability of selecting a pencil that is not blue.

Solution

To find the probability of selecting a pencil that is not blue, we need to determine the total number of pencils that are not blue and divide it by the total number of pencils in the box.

Let's calculate the probability step by step:

1. Total number of pencils in the box: 24. 2. Number of blue pencils: 24 - 13 = 11. 3. Number of pencils that are not blue: 24 - 11 = 13. 4. Probability of selecting a pencil that is not blue: (Number of pencils that are not blue) / (Total number of pencils in the box) = 13 / 24.

Therefore, the probability of selecting a pencil that is not blue is 13/24.

Answer

The probability of selecting a pencil that is not blue is 13/24.
