Answer:

0.5.

Explanation:

Number of red marbles = 50

Yellow marble = 40

Green marble = 10

Total number of marble = 50+ 40 + 10 = 100

Probability of getting yellow marble =
(40)/(100)

= 0.4

Probability of getting green marble =
(10)/(100)

= 0.1

Probability of getting either red or green marble = 0.4 + 0.1 = 0.5

Hence, the required probability is equal to 0.5.
