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
