2/ 17 because it’s 17 marbles and I hav a 2/17 chance of pulling 2 yellows
The answer to your question 29 is E 935,00. The way how I got this answer by multiplying 55 and 17,000 and by that the is E. For question 30 the answer is H. The way how I got this answer is by knowing twice means 2 times so by that H was the only one with 15+2n so by that I knew that was the answer.
Hope this helps:)
