• A. $\frac{10}{15}$
• B. $\frac{11}{15}$
• C. $\frac{9}{15}$
• D. none of these

Answer 1

Answer: (D)

none of these

A ball is drawn from a box containing 6 red balls, 4 blue and 5 green.

the ball will be red that white,$6+0=6$ 0 is number of white balls

the probability that the ball will be red or white

$P\left(E\right)=\frac{6}{6+4+5}=\frac{6}{15}$
