Answer 7

so it its all wrong

Answer 8

Sorry, my solution posting was incorrect.

Answer 9

Total no of marbles = 10
No. Of red marbles = 3
Probability of getting a red in the first attempt is 3/10
In the second attempt, only 9 marbles are left and of which only 2 are red.
Now the probability of getting another red becomes 2/9
So the probability of getting 2 consecutive reds is (3/10)*(2/9)=1/15

Answer 10

Is it clear now?
