How many brothers does everyone here have?
Answer:
a) 
b) 
c) 
d) 
e) The intersection between the set A and B is the element c so then we have this:

Step-by-step explanation:
We have the following space provided:
![S= [a,b,c,d,e]](https://tex.z-dn.net/?f=%20S%3D%20%5Ba%2Cb%2Cc%2Cd%2Ce%5D)
With the following probabilities:

And we define the following events:
A= [a,b,c], B=[c,d,e]
For this case we can find the individual probabilities for A and B like this:


Determine:
a. P(A)

b. P(B)

c. P(A’)
From definition of complement we have this:

d. P(AUB)
Using the total law of probability we got:

For this case
, so if we replace we got:

e. P(AnB)
The intersection between the set A and B is the element c so then we have this:

Y=2 by the method of substitution (x is 7).
18 divided by 6 is 3
when you add 3 with 4 it gives you 7
7 is your total answer
<span>5(2x - 1) = 6 (distribute the 5)
10x-5=6 (add 5 on both sides)
10x=11 (divide by 10 on both sides)
x=1.1
the answer is 1.1</span>
