Box contains 6 green marbles and 8 white marbles. the first marble was white marble, what is probability of choosing, without replacement, another white marble?

Question

I am not sure how to do this question. Even knowing the formula of how to do it would help because I am not for sure.

Answer 1

There are a total of 14 marbles in the box at the start. If you draw one marble and don't replace it, the box then has 13 marbles. How many white marbles are left once one has been drawn? The probability of finding another white marble is just the number of remaining white marbles divided by the total number of remaining marbles!

 

P = W/T

 

Where "W" is the number of white marbles left and "T" is the number of total marbles left. Remember, you took away one white marble!

 

I hope this helps, let me know if you need any more assistance!
