Answer:

10 red disks, 12 blue disks, 3 green disks

Explanation:

a)

experimental probability = frequency / total amount of tries

experimental prob. of red = 20 / 50

b)

find the experimental probability of each disk

20/50 x 25 = red disks

20/50 x 25 = 10

-

24/50 x 25 = blue disks

24/50 x 25 = 12

-

6/50 x 25 = green disks

6 / 50 x 25 = 3

-

Hope this makes sense!
