Number of red balls = 5  

Number of orange balls = 2

Number of yellow balls = 1

Number of green balls = 2

Therefore total number of balls = 10.

Probability of getting a ball =

 P(choosing orange ball) =  

After picking an orange ball, we are left with 9 balls

P ( choosing a green ball) =

P(choosing an orange marble and a green marble) =

0.04444 is the approximate probability of choosing an orange marble and a green marble.
