The answer is D .. one hundred random students from the sixth grade
If you roll a six sided dice once, each outcome has a 1/6 probability.
This means 4 has a 1/6 probability.
If you roll a dice 1200 times....
1200 × 1/6 = 1200/6 = 200
You would expect to get a 4 200 times.
GCF(24, 30, 42) = 6 I think it is.
13 16 15 19 20 15 19 20 14 15 17 18 and that's all i see hopes that helped :)
