Answer:
Concept: Binomial Multiplication
- (x-1)(x-9)
- x^2-9x-x+9
- x^2-10x+9
The one digit prime numbers are 2,3,5,7
Well, I'm going to guess the "x" is a multiplication sign. To solve this you have your equation (7/8 x c) and you replace c with 8. Now your equation is 7/8 x 8. To solve the fraction equation you do 7/8 x 8/1 or 7/ So the answer to this equation is 7. Please add as brainiest :)
Answer:
x = 23
Step-by-step explanation:
Considering the given probabilities, it is found that the correct option about whether the events are independent is given as follows:
p(x) · p(y) = p(x and y). They are independent because p(x) p(y) = p(x and y).
<h3>What are independent events?</h3>
Two events, A and B are independent, if:
![P(A \cap B) = P(A)P(B)](https://tex.z-dn.net/?f=P%28A%20%5Ccap%20B%29%20%3D%20P%28A%29P%28B%29)
Researching this problem on the internet, the probabilities are given as follows:
![P(X) = \frac{4}{5}, P(Y) = \frac{1}{4}, P(X \cap Y) = \frac{1}{5}](https://tex.z-dn.net/?f=P%28X%29%20%3D%20%5Cfrac%7B4%7D%7B5%7D%2C%20P%28Y%29%20%3D%20%5Cfrac%7B1%7D%7B4%7D%2C%20P%28X%20%5Ccap%20Y%29%20%3D%20%5Cfrac%7B1%7D%7B5%7D)
Hence:
![P(X)P(Y) = \frac{4}{5} \times \frac{1}{4} = \frac{1}{5} = P(X \cap Y)](https://tex.z-dn.net/?f=P%28X%29P%28Y%29%20%3D%20%5Cfrac%7B4%7D%7B5%7D%20%5Ctimes%20%5Cfrac%7B1%7D%7B4%7D%20%3D%20%5Cfrac%7B1%7D%7B5%7D%20%3D%20P%28X%20%5Ccap%20Y%29)
Hence the events are independent and the correct option is given by:
p(x) · p(y) = p(x and y). They are independent because p(x) p(y) = p(x and y).
