Answer:
12
Step-by-step explanation:
We can write the following ratio
1:3 (for every student who gets an A 3 gets a b)

Answer:
Each is equally likely (assuming a perfect die). The probability of rolling less than 7 is equal to the probability of rolling 1 or 2 or 3 or 4 or 5 or 6. That is 1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 6/6. Which is 1 or 100%.
Step-by-step explanation:
It would be 2:6, or 2 to 6.
