We can solve this problem using the binomial distribution. A binomial distribution<span> can be thought of as a success or failure outcome in an experiment or survey that is repeated multiple times.
</span>Probability function of binomial distribution has the following form:
![P= \frac{n!}{k!(n-k)!} p^k(1-p)^{n-k}](https://tex.z-dn.net/?f=P%3D%20%5Cfrac%7Bn%21%7D%7Bk%21%28n-k%29%21%7D%20p%5Ek%281-p%29%5E%7Bn-k%7D)
p represents the probability of each choice we want. k is the number of choices we want and n is the total number of choices.
In our case p=0.85, k=5 and n=6.
We can now calculate the answer:
![P= \frac{6!}{5!(6-5)!} 0.85^5(1-0.85)^{6-5}=0.39](https://tex.z-dn.net/?f=P%3D%20%5Cfrac%7B6%21%7D%7B5%21%286-5%29%21%7D%200.85%5E5%281-0.85%29%5E%7B6-5%7D%3D0.39)
The probability is 39%.

Answer:
2 books
Step-by-step explanation:
10 + 5x = 16 + 2x
- 2x - 2x
10 + 3x = 16
-10 -10
3x = 6
/3 /3
<u>x = 2</u>
Answer:
subtract 1 then divide 2
