Question

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

Answer 1

всего 17+23+19 = 59

23 - в фирме

вероятность того, что случайно встреченный выпускник работает в фирме

 

23/59 =0,39  = 39%

Answer 2

Probability of randomly meeting a graduate working in a firm

To find the probability that a randomly encountered graduate is working in a firm, we need to calculate the ratio of the number of graduates working in a firm to the total number of graduates.

Given the following information: - Number of graduates working in a bank: 17 - Number of graduates working in a firm: 23 - Number of graduates working in a tax inspection office: 19

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

Total number of graduates = Number of graduates in a bank + Number of graduates in a firm + Number of graduates in a tax inspection office

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

The probability of randomly meeting a graduate working in a firm is then:

Probability = Number of graduates working in a firm / Total number of graduates

Probability = 23 / 59

Probability = 0.3898 (or approximately 38.98%).

Please note that the above calculation assumes that each graduate has an equal chance of being randomly encountered.
