Answer:

1 D. 400 spins

2 C.4/20

3 A. 6/20

Step-by-step explanation:

1

The more times you run a probability-based trial, the more likely you are to get close to the theoretical frequency.

2

Since 1 and 2 represent goals, just find the options that have three/four 2's and 1's. These are 5212, 2152, 2512, and 2112. Since there are 4 options out of 20, we can say our probability is 4/20

C

Since 1 and 2 represent goals, we have to find the options where there are no 1's or 2's. These are 6643, 3554, 4533, 6634, 4536, and 5546. Since there are 6 options out of 20, we can say our probability is 6/20
