Given this result, of the answers given, we must say that at least 4 people will say cashews are their favorite nut.
I know two ways that we can use in this problem, it depends on your knowledge in your math class.
The first way is using the combinatorial formula, and probability:
P = possibles outcomes from the event/ all outcomes from the experiment
Using combinatoria P = (2C2*4C1)/(6C3)
2C2 is the possibles ways to get two defectives and we calculate that:
2C2=2!/(2!*(2-2)!)=1
Then, 4C1 is the possibles ways to get 1 no defective (remember you need only 3 test and you expect 2 are defective from the question), calculating:
4C1=4!/(1!*(4-1)!)=4
And 6C3 represents the all possible ways to get 3 calculators (no matter if they defective or not), calculating:
6C3=6!/(3!*(6-3)!)=20
Apply p formula:
<span>P = (1*4)/20 = 1/5 = 0.2</span> in percertage 20%
The another way to calculate this problem is using the tree diagram or multiplication rule:
P=(2/6)*(1/5)*(4/4)=1/15 (here you are saying the order of computer, first and second defective and the last one no defective)
P=(2/6)*(4/5)*(1/4)=1/15 ( the second is no defective, and the others are defective)
P=(4/6)*(2/5)*(1/4)=1/15 (the first one is no defective and the others are defective)
Finally add the three result above, and get the answer:
<span>P=1/15+1/15+1/15 = 3/15 = 1/5 = </span>0.2

If you put them in order, least to greatest and cross off each end till you reach the middle. mean is all the number added up then divided by how many numbers are listed
Answer:
Step-by-step explanation:
Coordinates of B is (3,-4)
You multiply -2 by 2 to get -4 and then create the equation then you substitue -7 for +7 and add +7 to -4 which gives you 3 (x coordinate of B)
You multiply -1 by 2 to get -2 and then create the equation then you subtract 2 by -2 which gives you -4 (y coordinate of B)
To check your answer use the midpoint formula
which will give you the midpoint (-2,-1)
Answer:
