Question

В соревнованиях по теннису участвуют 26 спортсменов, из них 15 из России. Какова вероятность, что спортсмен из России Витя будет играть с русским?

Answer 1

Ответ 0.56 , так как без вити участников 25, и россиян тогда 14, следовательно 14 делим на 25 получаем 0.56

Answer 2

Probability of Russian Player Vitya Playing with a Russian

The probability of the Russian player Vitya playing with a Russian in the tennis competition can be calculated using the total number of players and the number of Russian players.

Given: - Total number of players = 26 - Number of Russian players = 15

The probability can be calculated using the formula: Probability = (Number of favorable outcomes) / (Total number of outcomes)

In this case, the favorable outcome is Vitya playing with a Russian, and the total number of outcomes is the total number of players.

Using the given information: Number of favorable outcomes = Number of Russian players - 1 (excluding Vitya) Total number of outcomes = Total number of players

Therefore, the probability can be calculated as: Probability = (15 - 1) / 26

Let's calculate the probability.
