A box contains 6 green marbles and 14 white marbles. If the first marble chosen was a white marble, what is the probability of choosing, without replacement, another white marble?

Question

Express your answer as a fraction or a decimal number rounded to four decimal places.

Answer 1

"Without replacement" means that the white marble initially drawn has not been put back into the box after taking it out. Therefore, the updated marble count in the box is 6 green, 13 white. The probability of choosing another white marble is the ratio of white marbles to total marbles in the box, which is 13/19.

Hope that helps!
