Answer 2

Calculating the Probability of an Argentine Diver Performing Fourteenth

To calculate the probability of an Argentine diver performing fourteenth in the diving competition, we can use the following information:

- Total number of divers: 40 - Number of divers from the Netherlands: 6 - Number of divers from Argentina: 2

The probability can be calculated using the formula: \[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]

Given that the order of performances is determined by drawing lots, the probability of an Argentine diver performing fourteenth can be calculated as follows:

\[ \text{Probability} = \frac{1}{40} \]

This is because there is only one favorable outcome (an Argentine diver performing fourteenth) out of a total of 40 possible outcomes (the order of all divers' performances).

Therefore, the probability of a diver from Argentina performing fourteenth is 1/40.

Conclusion

The probability of a diver from Argentina performing fourteenth in the diving competition is 1/40.
