Answer 1

4/25=0,16 - искомая вероятность

Answer 2

Probability of the Last Competitor Being from the Czech Republic in the European Athletics Championships

To calculate the probability of the last competitor being from the Czech Republic in the European Athletics Championships in the long jump event, we need to know the total number of competitors and the number of competitors from the Czech Republic.

According to the information provided, there are 25 athletes participating in the long jump event, with 4 of them representing the Czech Republic.

To calculate the probability, we divide the number of Czech athletes by the total number of athletes:

Probability = Number of Czech athletes / Total number of athletes

In this case, the probability would be:

Probability = 4 / 25

Calculating this, we find that the probability of the last competitor being from the Czech Republic is approximately 0.16 or 16%.

Please note that this calculation assumes that all athletes have an equal chance of being the last competitor, and it does not take into account any specific factors or conditions that may affect the order of the competitors.
