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%.
Answer:
1/4
Step-by-step explanation:
Given an event A and event B, the probability of both happening can be determined by multiplying the two individual probabilities.
We can start by finding the individual probabilities
The probability of rolling an odd number is 3/6 = 1/2, as there are 3 odd numbers (1,3,5) on a die and 6 possibilities total. Furthermore, there is a equal chance of rolling each number as it is a fair die
The probability of flipping a head is 1/2, as there are two equal possibilities (heads and tails), with one of them being heads
To find the probability of both happening, we can multiply them to get (1/2) * (1/2) = 1/4
Answer:
21 m²
Step-by-step explanation:
Area of a trapezoid is given by the formula:
A = (a+b)/2×h
(where h is the vertcial height, and a and b are the parallel lines)
Substituting values given gives us:
A = (5+9)/2×3
A = 14/2×3
A = 7×3
A = 21
Units will be m² as this is area.
Answer:
7/6
Step-by-step explanation:
To find the slope of a line between two points
m = (y2-y1)/ (x2-x1)
= (6--1)/(9-3)
= (6+1)/(6)
= 7/6
