A bag contains 6 black and 8 white balls. 1 ball is drawn at random. What is the more probability that the ball drawn is white?

3/7

1/8

4/7

3/4

Total number of balls = 6 black + 8 white = 14 balls

Number of white balls = 8

Probability of drawing a white ball = Number of white balls / Total number of balls

= 8/14

= 4/7

So, the probability of drawing a white ball is 4/7.
