An Olympic archer is able to hit a bulls-eye 86% of the time. Assume each shot is independent of the others. If she shoots 12 arrows, what is the probability that 18. She never misses?
19. She gets exactly 11 bulls-eyes?
20. She gets between 6 and 10 bulls-eyes?
21. She gets less than 8 bulls-eyes?
22. She gets at least 8 bulls-eyes?
23. She gets at most 9 bulls-eyes?
24. She gets between 9 and 12 bulls-eyes, inclusive?
25. What is the expected number of bulls-eyes for the 12 attempts?

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

i think that you should ask google for the answer to that problem because if we don't know it google does

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
