Question

Выпускники экономического института работают в трех различных компаниях: 17 человек в банке, 23 фирме и 19 в налоговой.найдите вероятность того что случайно встреченный ученик работает в фирме

Answer 1

всего человек 17+23+19=59 человек

в фирме работает 23 человека.

значит вероятность того что случайно встреченный ученик работает в фирме равна: (59-36)/59=0,39(это приблеженное значение)

Answer 2

Probability of randomly meeting a student working in a specific company

To find the probability of randomly meeting a student who works in a specific company, we need to calculate the ratio of the number of students working in that company to the total number of graduates from the economic institute.

Given the following information: - 17 graduates work in a bank. - 23 graduates work in a firm. - 19 graduates work in the tax office.

We can calculate the total number of graduates by summing up the number of graduates in each company:

Total number of graduates = 17 + 23 + 19 = 59

To find the probability of randomly meeting a student who works in a specific company, we divide the number of graduates working in that company by the total number of graduates:

Probability = Number of graduates working in the specific company / Total number of graduates

Let's calculate the probabilities for each company:

1. Bank: - Number of graduates working in the bank = 17 - Probability of randomly meeting a student working in the bank = 17 / 59 = 0.2881 2. Firm: - Number of graduates working in the firm = 23 - Probability of randomly meeting a student working in the firm = 23 / 59 = 0.3898 3. Tax office: - Number of graduates working in the tax office = 19 - Probability of randomly meeting a student working in the tax office = 19 / 59 = 0.3220 Please note that these probabilities are based on the given information and assume that the distribution of graduates across companies is uniform.
