Answer:
Step-by-step explanation:
Given
To make A as the subject of the formula we need to rearrange
Divide by throughout we get
Suppose P(E) = 81%; P(E and F) = 9%; and P(E or F) = 65%,
1 answer:
Using Venn probabilities, it is found that P(F) = -0.07, which is not a probability, as it is a negative value.
------------------
- We have two events, E and F.
- Their probabilities are:
- The probabilities are related by the following equation:
- Replacing into the equation, we can find P(F).
P(F) = -0.07, which is not a probability, as it is a negative value.

So hmm checking the picture below
you can pretty much just use the pythagorean theorem to get the missing adjacent side
once you have that, you just get the cosine since the cosine is just adjacent/hypotenuse
as far as the sum with θ, those angles would be in your Unit Circle surely
and just expand the sum identity with those values
