Question

Научная конференция проходит 5 дней. Все выступления поровну распределены между днями конференции. Порядок выступлений определяется жеребьевкой. Какова вероятность, что выступление доктора наук К. из России состоится во второй день конференции?

Answer 1

Чтобы найти вероятность, нужно кол-во благоприятных случаев поделить на кол-во всех случаев.
благоприятный случай-это выступление во 2 день, а все случаи это выступления во все 5 дней, значит нужно 1/5=0,2
ответ 0,2

Answer 2

Probability of Doctor K's Presentation on the Second Day of the Conference

To calculate the probability of Doctor K's presentation occurring on the second day of the conference, we need to consider the total number of days and the number of possible outcomes.

Given that the conference lasts for 5 days and all presentations are equally distributed among those days, there are 5 possible outcomes for Doctor K's presentation day.

Since the order of presentations is determined by a lottery, each day has an equal chance of being selected for Doctor K's presentation. Therefore, the probability of Doctor K's presentation occurring on the second day is 1/5 or 0.2 (20%).

Please note that the specific details about Doctor K's presentation and the conference were not provided in the question, so the answer is based on the given information and assumptions about the distribution of presentations.
