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

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

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

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

Given that ∠CEA is a right angle and bisects ∠CEA, which statement must be true?

loris [4]

Given that ∠CEA is a right angle which has been bisected by BE, then:
∠CEB=∠BEA
thus each angle will be complementary to each other, hence the size will be:
90/2=45°
hence the correct statement.
m∠CEB = 45°

Find the common ratio of the geometric sequence 18,-72,288,...

tamaranim1 [39]

Answer:

The common ratio of the geometric sequence is -4

Step-by-step explanation:

Geometric Sequence

A geometric sequence is defined as a series of numbers that follow a fixed pattern: Each term equals the previous term times a fixed number called the common ratio. The recursive formula is:

$a_n=a_{n-1}*r$

Where r is the common ratio.

We are given three terms of a geometric sequence:

18,-72,288,...

To find the common ratio, just divide each term by the previous term:

$\displaystyle r=\frac{-72}{18}=-4$

Make sure it's a fixed number and test with the third term:

$\displaystyle r=\frac{288}{-72}=-4$

Since both numbers coincide, the common ratio of the geometric sequence is -4
