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

$\frac { 3 } { 4 }$

$\frac {4 } { 7 }$

$\frac { 1 } { 8}$

$\frac {3 } { 7 }$

Answer : Option B

Explanation :

Let number of balls = (6 + 8) = 14.

Number of white balls = 8.

p(drawing a white ball) = $\frac {8 } { 14 }$ = $\frac {4 } { 7 }$
