Answer:
D
Step-by-step explanation:
total marbles
9
red marbles- 4
so prob is 4/9 or D
if my answer helps please mark as brainliest
4/5 is greater than 0.75. That is because, if you turn 4/5 into a decimal, them that decimal will be equal to 80/100. 0.75 is 75/100 as a fraction. 80/100 (4/5 simplified) compared to 75/100 is greater. The answer is yes.
Y = 2x + 4 and y = 3x + 1
Therefore, 2x + 4 = 3x + 1
It would be 66.3 because 2% Coverts to .02 then you multiply that to 65 and get 1.3 and then you add that to 65
Answer:
![Probability = \frac{2}{35}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B2%7D%7B35%7D)
Step-by-step explanation:
Given
![Total = 70](https://tex.z-dn.net/?f=Total%20%3D%2070)
First, we need to list the multiples of 5
![M_5 = \{5,10,15,20,25,30,35,40,45,50,55,60,65,70\}](https://tex.z-dn.net/?f=M_5%20%3D%20%5C%7B5%2C10%2C15%2C20%2C25%2C30%2C35%2C40%2C45%2C50%2C55%2C60%2C65%2C70%5C%7D)
Then, multiples of 3![M_3 = \{3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,63,66,69\}](https://tex.z-dn.net/?f=M_3%20%3D%20%5C%7B3%2C6%2C9%2C12%2C15%2C18%2C21%2C24%2C27%2C30%2C33%2C36%2C39%2C42%2C45%2C48%2C51%2C54%2C57%2C60%2C63%2C66%2C69%5C%7D)
Next, is to list out the common elements in both
![M_3\ n\ M_5 = \{15,30,45,60\}](https://tex.z-dn.net/?f=M_3%5C%20n%5C%20M_5%20%3D%20%5C%7B15%2C30%2C45%2C60%5C%7D)
![n(M_3\ n\ M_5) = 4](https://tex.z-dn.net/?f=n%28M_3%5C%20n%5C%20M_5%29%20%3D%204)
The required probability is then calculated as thus:
![Probability = \frac{n(M_3\ n\ M_5)}{Total}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7Bn%28M_3%5C%20n%5C%20M_5%29%7D%7BTotal%7D)
![Probability = \frac{4}{70}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B4%7D%7B70%7D)
![Probability = \frac{2}{35}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B2%7D%7B35%7D)
