A ball is drawn from a box containing $6$ red balls, $4$ blue and $5$ green. Calculate What is the probability that the ball will be red or white?

The correct option is A 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

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