A bag contains

4

white balls,

5

red balls,

2

black balls and

4

green balls.

Total numbers of balls

= 4 + 5 + 2 + 4 = 15

Total numbers of red and white balls

= 5 + 4 = 9

Probability is given by,

P (A)

= \frac{no. of possible outcomes}{No. of total outcomes}

P

(red or white ball)

= \frac{9}{15} = \frac{3}{5}
