Step-by-step explanation:
Head : red, blue, yellow
Tails : red, blue yellow
The answer is 4/36 or 1/9.
The chances of one dice getting 6 = 1/6. whereas, the chances of getting a combination of 9 or higher with at least one dice getting 6 is: 1/6* 4/6 since there can only be four combinations that would sum to 9 (3 +6, 4+6, 5+6 & 6+). 1/6 * 4/6 = 4/36 or 1/9.
