Answer:
shown in steps, either 189/15625 or 63/4600 depends on different situation
Step-by-step explanation:
The answer depends on whether the is chip can be put into bin for next pick,
if it can be put back after first pick.. the possibility will be
total chips: 7 + 9 + 3 + 6 = 25
Red -> green -> yellow 7/25 x 9/25 x 3/25 = 189/15625
If the first time picked chip will not put back for second pick:
7/25 x 9/24 x 3/23 = 63/4600
