The probability that Paul wins in a raffle is given by the expression
AnnZ [28]

Answer:

1 - p

Step-by-step explanation:

Consider the (\Omega, \mathcal{F}, \mathbb{P}) where \mathcal{F} is sigma algebra and \mathbb{P} is probabilistic measure. Denote A \subset \Omega where Paul wins. By additivity of measure we know that

\mathbb{P}(A) + \mathbb{P}(\Omega \setminus A) = \mathbb{P}(\Omega) = 1.

So

\mathbb{P}(\Omega \setminus A) = 1 - \mathbb{P}(A) = 1 - p.

But \Omega \setminus A is exactly the set where Paul does not win. Q.E.D.

Which equation represents the line that passes through (-3,5) and is parallel to the graph of y= -2/3x+5
Nostrana [21]
Parallel to the graph of y = -2/3x + 5
means that it has the same slope

Rewrite
y = -2/3x + b
plug in the given coordinates to solve for b
5 = -2/3(-3) + b
5 = 2 + b
subtract 2 from both sides
3 = b

plug that back into the equation
y = -2/3x + b
y = -2/3x + 3

The answer is <span>B. y= -2/3x+3</span>

This line is parallel to y = -2/3x + 5 and it passes the point (3, 5).

Hope this helps :)
