1. 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?

A. $\frac{3}{4}$

B. $\frac{4}{7}$

C. $\frac{1}{8}$

D. $\frac{3}{7}$

Solution:

\begin{aligned} Let number of balls \\ = (6 + 8) \\ = 14 \\ Number of white balls = 8 \\ P (drawing a white ball) \\ = \frac{8}{14} = \frac{4}{7} \end{aligned}
