Answer:

Step-by-step explanation:

The total number of ducks in the pond is 75. 25 ducks are marked as a winner.

Probability is expressed as number of possible outcomes/total number of outcomes.

if you take 2 ducks out but don't replace them, the probability that the first duck that you took out is a winner is

25/75 = 1/3

The total number of ducks left would be 74 and the number of winners would be 24.

the probability that the second duck that you took out is a winner is

24/74 = 12/37

Therefore, the probability that both are winners is

1/3 × 12/37 = 4/37
