Ответ:
The chance of taking a red marble out of the bag would be 8/28=4/17. The probability of taking out ANOTHER red marble would be 7/27 because if you took a marble out the total would be one less, 28-1=27. And if it is red, than 8-1=7. Using this it will be easier to find the answer to your question. Good luck.
