Question

В сборнике билетов по математике всего 25 билетов, в 10 из них встречается вопрос по логарифмам. Найдите вероятность того, что в случайно выбранном на экзамене билете школьнику достанется вопрос по логарифмам.

Answer 1

Вероятность расчитывается по формуле:
Z1/Zn
10/25=2/5

Answer 2

10/25 = 0,4 вероятность того, что в случайно выбранном на экзамене билете школьнику достанется вопрос по логарифмам. 

Answer 3

Probability of Getting a Logarithm Question in a Randomly Selected Exam Ticket

To find the probability of getting a logarithm question in a randomly selected exam ticket, we need to determine the number of tickets that contain a logarithm question and divide it by the total number of tickets.

According to the information provided, there are 25 tickets in total, and 10 of them contain a question on logarithms.

Therefore, the probability can be calculated as follows:

Probability = Number of tickets with logarithm questions / Total number of tickets

Probability = 10 / 25

Simplifying the fraction, we get:

Probability = 2 / 5

So, the probability that a randomly selected exam ticket will have a question on logarithms is 2/5.

Please note that the search results did not provide specific information about the number of tickets with logarithm questions. However, based on the given information, we can make the assumption that there are 10 tickets with logarithm questions out of the total 25 tickets.
