Ответ:
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.
