has 5 red, 8 white, 4 green marbles.

the probability that the marble taken out will be red is

total no. of possible outcomes

no. of favourable outcomes

.

5

=0.29

the probability that the marble taken out will be white is

total no. of possible outcomes

no. of favourable outcomes

.

⇒

5+8+4

8

=0.47

the probability that the marble taken out will be green is

total no. of possible outcomes

no. of favourable outcomes

.

5+8+4

5+8
