Answer:

Step-by-step explanation:
Answer:
C) 0.179
Step-by-step explanation:
Since the trials are independent, this is a binomial distribution:
<u>Recall:</u>
- Binomial Distribution -->
denotes the probability of
successes in
independent trials
denotes the probability of success on each of
trials
denotes the probability of failure on the remaining
trials
denotes all possible ways to choose
things out of
things
<u>Given:</u>
<u>Calculate:</u>
Therefore, the probability that the archer will get exactly 4 bull's-eyes with 10 arrows in any order is 0.179
0.476 is the answer to this question.
Answer:
Step 1 : <u>1000</u> * 2 * 9
Step 2 : <u>1000</u> * 18
Step 3 : <u>18000</u>
Step-by-step explanation:
<u>Step 3</u>
2000 * 9 = y ⇒ 18000
y = <u>18000</u>
<u>Step 1</u>
Solving for this, we have:
Let a be the unknown variable
a * 2 * 9 = 18000
18a = 18000
a = <u>1000</u>
Therefore, when we multiply 1000 by 2 & 9, we have 18000
<u>Step 2</u>
Solving for this, we have:
Let a be the unknown variable
a * 18 = 18000
18a = 18000
a = <u>1000 </u>
Therefore, when we multiply 1000 by 18, we have 18000
<u>We therefore see that the value of the unknown variables (a, y) is shown above & the product of all the steps (step 1 - 3) is 18000</u>
