Answer:
9
Step-by-step explanation:
For one throw the probability of a miss is 1/2 since there are just two outcomes
Similarly for one throw the probability of a score is 1/2 since there are two outcomes.
Therefore for 8 trials we expect at least for different trials starting from 1
8 miss 0 score
7 miss 1 score
6 miss 2 score
5 miss 3 score
4 miss 4 score
3 miss 5 score
2 miss 6 score
1 miss 7 score
0 miss 8 score
So the number of possible outcomes is 9
And this define by what we call the binomial probability and is defined as
