Answer 3

Probability of John Smith, an American, performing third in the competition

To find the probability of John Smith, an American athlete, performing third in the competition, we need to consider the total number of athletes and the number of possible outcomes.

Given that there are 7 athletes from the USA, 3 from Sweden, 4 from Mexico, and 6 from Germany, the total number of athletes is:

7 (USA) + 3 (Sweden) + 4 (Mexico) + 6 (Germany) = 20 athletes

Since the order of performance is determined by a random draw, there are 20 possible outcomes for the order of the athletes.

To calculate the probability of John Smith, an American athlete, performing third, we need to determine the number of favorable outcomes where John Smith is the third performer.

Since there are 7 American athletes, the probability of John Smith being the third performer is:

1 (John Smith) / 20 (total athletes) = 1/20

Therefore, the probability of John Smith, an American athlete, performing third in the competition is 1/20.
