Question

If a bag contains 6 red balls and 8 blue balls, and you pull one ball from the bag, which is blue, what is the probability that the next ball you pull will be red?

Answer 1

Total number of balls is $=6+8=14balls$

Probability to pull one blue ball $=\frac {8}{14} =\frac {4}{7}$

Making the total number of balls reduce from $14$ to $13$

Hence

Probability that next ball is red $=\frac{6}{13}$
