Quentin Hudson · Answer 1

The probability is 1/10 and the third question would be b. c. and d.

Dalia · Answer 2

2) 2/10 is the probability of picking red. 5/9 is the chance of picking green the second time because one marble has been taken out. Multiply the probabilities together and should get the answer 1/9

3) I think B, C, D but C, might not be right
