We are to choose 2 red beetles out of 3 and 2 are red.
The probability for choosing Red 1 is: 2/3 ( because 2 are red)
According to AAMC, the probability for choosing Red 2 is : 2/3 ( because 2 are red).
But if you already picked one beetle, the remaining total would be 2, so wouldn't the probability for picking Red be 1/2?
Nowhere in the question does it say that the experiment is done with replacement, and since the number of offspring does is constant, the probabilities would change...
