В сборнике билетов по географии всего 40 билетов, в 14 из них встречается вопрос по странам Европы. Найдите вероятность того, что в случайно выбранном на экзамене билете школьнику достанется вопрос по странам Европы.

Answer 1

Вероятность этого будет 14/40 (четырнадцать к сорока) т.е. 7/20 (семь к двадцати)

Answer 2

Calculation of Probability

To find the probability that a randomly chosen exam ticket will have a question about European countries, we need to determine the ratio of the number of tickets with European country questions to the total number of tickets.

Given: - Total number of tickets: 40 - Number of tickets with European country questions: 14

The probability can be calculated as follows:

Probability = Number of tickets with European country questions / Total number of tickets

Probability = 14 / 40

Probability = 0.35

Therefore, the probability that a randomly chosen exam ticket will have a question about European countries is 0.35 or 35%.

Please note that the search results provided by You.com did not contain specific information about the number of tickets with European country questions. However, the calculation above is based on the given information in the user's question.
