Answer and Step-by-step explanation:
The computation is shown below:
Let us assume that
Spam Email be S
And, test spam positive be T
Given that
P(S) = 0.3
Now based on the above information, the probabilities are as follows
i. P(Spam Email) is
= P(S)
= 0.3
= 1 - 0.3
= 0.7
ii.
= 0.8906
iii.
= 0.0221
We simply applied the above formulas so that the each part could come
So we know that an average is the sum of the scores divided by the number of scores that were added together. In this case we are going to be dealing with 4 tests. So let's say x is the score for our fourth test. We can create this equation:
So then we need to simplify the top:
Then multiply by 4 on both sides to get rid of the denominator:
Then solve for x:
So now we know that Sam needs to score a 67 on the fourth test to have an average score of 50.
