Question

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

Answer 1

Ответ:

Пошаговое объяснение:

25-10=15 билетов в которых нет неравенства

P=15/25=0,6 -  вероятность того, что в случайно выбранном на экзамене билете школьнику не достанется вопроса по неравенствам

Answer 2

Probability of not getting a question on inequalities in a randomly chosen exam ticket

To find the probability that a student does not get a question on inequalities in a randomly chosen exam ticket, we need to determine the number of exam tickets that do not have a question on inequalities and divide it by the total number of exam tickets.

According to the information provided, there are 25 exam tickets in total, and 10 of them have a question on inequalities Therefore, the number of exam tickets without a question on inequalities is 25 - 10 = 15.

The probability of not getting a question on inequalities can be calculated as:

Probability = Number of favorable outcomes / Total number of outcomes

In this case, the number of favorable outcomes is 15 (exam tickets without a question on inequalities), and the total number of outcomes is 25 (total number of exam tickets).

Therefore, the probability of not getting a question on inequalities in a randomly chosen exam ticket is:

Probability = 15 / 25 = 0.6

So, the probability is 0.6 or 60%.
