Answer:
98.01% probability of getting 5 clean sheets
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, the order that the sheets are chosen is not important, so we use the combinations formula to solve this problem.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
![C_{n,x} = \frac{n!}{x!(n-x)!}](https://tex.z-dn.net/?f=C_%7Bn%2Cx%7D%20%3D%20%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7D)
0.4% of the sheets contain spots
Of 500, that is 0.004*500 = 2.
What is the probability of getting 5 clean sheets although 0.4% of the sheets contain spots?
Desired outcomes
2 are defective, so 5 sheets from a set of 500 - 2 = 498.
![D = C_{498,5} = \frac{498!}{5!493!} = 250160254344](https://tex.z-dn.net/?f=D%20%3D%20C_%7B498%2C5%7D%20%3D%20%5Cfrac%7B498%21%7D%7B5%21493%21%7D%20%3D%20250160254344)
Total outcomes
5 sheets from a set of 500.
![T = C_{500,5} = \frac{500!}{5!495!} = 255244687600](https://tex.z-dn.net/?f=T%20%3D%20C_%7B500%2C5%7D%20%3D%20%5Cfrac%7B500%21%7D%7B5%21495%21%7D%20%3D%20255244687600)
Probability:
![P = \frac{D}{T} = \frac{250160254344}{255244687600} = 0.9801](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7BD%7D%7BT%7D%20%3D%20%5Cfrac%7B250160254344%7D%7B255244687600%7D%20%3D%200.9801)
98.01% probability of getting 5 clean sheets
Answer:
6/17
Step-by-step explanation:
12/18 * 9/17
use 9 to divide 18 u'll be left with
12/2 * 1/17
use 2 to divide 12 u'll be left with
6/1 * 1/17
now u'll multiply leaving you with
6/17 as the final answer or u can also convert to decimal your answer will be
0.352 by approximation.

Answer:
c.
Step-by-step explanation:
Answer:
Slope: -2
y-intercept: -3 or (0, -3)
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
6x+3y= -9
3y = -6x - 9
y = -2x - 3
