Events A and B are such that P(A) = 3 8 , P(B) = 2 7 and P(A ∩ B) = 1 7 Work out P(A|B)
1 answer:
Answer:
Step-by-step explanation:
Given: Events A and B are such that and P(A∩B) = 17
To find:
Solution:
Probability refers to the chances of occurrence of any event.
An event is described as an outcome of a random experiment.
A random experiment is an experiment for which outcomes cannot be predicted.
P(A∩B) ÷ P(B) =

We are given the function below;
PART A
We then proceed to find if the function has a minimum or maximum value. To find if the function has a minimum or maximum value. If the x^2 coefficient is positive, the function has a minimum. If it is negative, the function has a maximum.
ANSWER: From the above, we can see that x^2 is negative, hence the function has a maximum
PART B and C
To find the minimum or maximum value, we would plot the graph of the f(x). The graph can be seen below.
From the graph, the black point helps answer part A and part B.
ANSWER: The function's maximum value is f(x)=2.
This is the point where the slope of the graph is equal to zero
ANSWER: The maximum value then occurs at x= -1
We can also solve this by differentiating the function.
To write the given phrase as an algebraic expression you can identify what does each part of the phrase mean:
59 less than: You have to substract 59 to the other part of the phrase
twice a number: as the number is n, twice a number is 2n
Then, you get the next algebraic expression:
