Question

В сборнике билетов по физике всего 25 билетов, в 11 из них встречается вопрос по термодинамике. Найдите вероятность того, что в случайно выбранном на экзамене билете школьнику достанется вопрос по термодинамике.

Answer 1

11-(билеты которые нужно получить) делим на 25-(общ кол во билетов) 

получается ответ 0.44

Answer 2

вероятность = число благоприятных исходов / число всех исходов

 

в данном случае она равна 1/25 или 0,44

 

Ответ 0,44

Answer 3

Probability of getting a thermodynamics question in a randomly selected exam ticket

To find the probability of getting a thermodynamics question in a randomly selected exam ticket, we need to determine the ratio of the number of thermodynamics questions to the total number of questions in the exam.

According to the information provided, there are 25 tickets in total, and 11 of them contain a question on thermodynamics.

Therefore, the probability can be calculated as follows:

Probability = Number of thermodynamics questions / Total number of questions

Probability = 11 / 25

Probability = 0.44

Therefore, the probability of a student getting a thermodynamics question in a randomly selected exam ticket is approximately 0.44 or 44%.

Please note that the probability is calculated based on the information provided and assumes that all tickets have an equal chance of being selected.
