Answer:
The probability of a chain defect is 3%.
Step-by-step explanation:
Given : A bicycle manufacturer is studying the reliability of one of its models. The study finds that the probability of a brake defect is 4 percent and the probability of both a brake defect and a chain defect is 1 percent.
If the probability of a defect with the brakes or the chain is 6 percent
To find : What is the probability of a chain defect?
Solution :
Let A be the event of brake defect
and B be the event of chain defect.
We have given, P(A)= 4%=0.04
P(A and B) = 1%=0.01
P(A or B)= 6%=0.06
We have to find P(B),
The formula used is,
Substitute the value,
or 
Therefore, The probability of a chain defect is 3%.
I would think that the answer would be angle
For this kind of questions, what you can do is to find a point on the figure and see what translations it does.
For example, you can find the point (4,2) on the figure H. And then look at each choices to see if the statement is correct.
For this question, the answer is B. The point (4,2) finally change to the (4,-8) on the figure H'. It has a vertical translation of 10 units down.

slot method
1st slot has 6 options to chose from
2nd slot has 5 since 1 is gone to slot 1
3rd slot has 4 since 2 are gone to 1st and 2nd slots
so it is
6 times 5 times 4=120
answer is 120 ways
Answer:
5/7 gallons of water for each rose bush
Step-by-step explanation:
we know that
To find out the amount of water that Elena give to each rose bush, divide the total gallons of water by the number of rose bushes
so
