Question

Выпускники экологического факультета работают в трех различных компаниях:19 человек-в банке;31-в фирме;15-в налоговой инспекции.Найдите вероятность того,что случайно встреченный выпускник работает в банке?

Answer 1

Общее число выпускников = 19+31+15=65. В банке работает 19 человек, тогда вероятность встречи работника банка = 19/65

Answer 2

Calculation of Probability

To find the probability that a randomly encountered graduate works in a bank, we need to divide the number of graduates working in a bank by the total number of graduates.

Given the following information: - 19 graduates work in a bank - 31 graduates work in a firm - 15 graduates work in a tax office

The total number of graduates is the sum of these three groups: 19 + 31 + 15 = 65.

Therefore, the probability that a randomly encountered graduate works in a bank is:

P(Bank) = Number of graduates working in a bank / Total number of graduates = 19 / 65 ≈ 0.2923.

So, the probability is approximately 0.2923 or 29.23%.
