We will be using the fact that , where
is the probability that the first bulb works and
is the probability that the second bulb works.
The probability that the first bulb works is . However, when we take one out (given that the first bulb works) we now have 19 working bulbs and 4 bad ones. This means that the probability that the second bulb works is
.
Now, we can find our final probability:
Answer:
(b) and (c) are true
Step-by-step explanation:
Given
Function A and B
First, calculate the slope of A
The equation of function A is:
The general form of a function is:
Where and
This implies that:
For function B:
By comparison:
(b) and (c) are true
