Answer:
Therefore the probability that he was taught by method A is 0.78.
Explanation:
<h3>Probability:</h3>The ratio of the number of favorable outcomes to the number of all possible outcomes.
<h3>Bayes' Rule:</h3>If the events ,
, .....
from a portion of a sample space S and A is any events of A, then
Given that,
There are two available method for teaching A and B.
The failure rate for A is 35%
That is P(F|A) =35%=0.35
The failure rate for B is 15%
That is P(F|A) =15%=0.15
A used 40% of the time.
P(A)=40%=0.40
B used 60% of the time.
P(A)=60%=0.60
To find P(A|F) , we use the Bayes's rule.
=0.78
Therefore the probability that he was taught by method A is 0.78.
Answer:
{-2, -14, -26, -50}
Step-by-step explanation:
The range of the function is the function evaluated at each point of the given domain. So to find the range of the function we need to find the value of the function for each point in the domain:
- For x = -8
The first value of the range of the function is -2
- For x = -2
The second value of the range is -14
- For x = 4
Th third values of the range is -26
- For x = 16
The fourth and last value of the range is -50
Now we can put all the values of the range together
The range of the function is {-2, -14, -26, -50}
