Question

В соревновании принимают участие 29 спортсменов. С помощью жребия выбирают двух спортсменов. Какова вероятность того, что спортсмен К., участвующий в соревновании, будет выбран?

Answer 1

Ответ:

2/29

Пошаговое объяснение:

если один спортсмен, то 1/29  2 — 1/29*2=2/29.

Answer 2

Probability of Sporstman K being chosen

To calculate the probability of Sporstman K being chosen, we need to determine the total number of possible outcomes and the number of favorable outcomes.

Given that there are 29 sportsmen participating in the competition and two will be chosen through a draw, the total number of possible outcomes is the number of ways to choose 2 sportsmen out of 29. This can be calculated using the combination formula:

Total number of possible outcomes = C(29, 2)

Using the combination formula, we can calculate the total number of possible outcomes as follows:

Total number of possible outcomes = 29! / (2! * (29 - 2)!)

Simplifying the expression:

Total number of possible outcomes = 29! / (2! * 27!)

Now, we need to determine the number of favorable outcomes, which is the number of ways Sporstman K can be chosen. Since only one sportsman K is participating, the number of favorable outcomes is 1.

Therefore, the probability of Sporstsman K being chosen is:

Probability = Number of favorable outcomes / Total number of possible outcomes

Substituting the values:

Probability = 1 / (29! / (2! * 27!))

Please note that the exact value of the probability cannot be determined without knowing the specific values of the sportsmen and the draw process. However, the formula provided above can be used to calculate the probability once the specific values are known.
