Yo sup??

To find P(A and C) we have to simply multiply the probabilities of getting an A with that of getting a C

P(A)=0.6

P(C|A)=0.3

P(A and C)=0.6*0.3

=0.18

Hope this helps.

A prize wheel is divided into 12 equally likely spaces labeled 1 to 12.

Answer:

Events E and F are independent.

Step-by-step explanation:

E = {multiple of 3} = {3, 6, 9, 12}

P(E) = 4/12

F = {even number} = {2, 4, 6, 8. 10, 12}

P(F) = 6/12

E and F = {even and multiple of 3} = {6, 12}

P(E∩F) = 2/12

In order for two events to be independent the following relationship must be true:

$P(E)*P(F) = P(E\cap F)$

Testing this property:

$P(E)*P(F) = \frac{4}{12}*\frac{6}{12}=\frac{24}{144}=\frac{1}{6} \\P(E\cap F) = \frac{2}{12}=\frac{1}{6} \\P(E)*P(F) = P(E\cap F)$

The relationship holds true, thus events E and F are independent.

Let's take this problem step-by-step:

First let's set up the equation for the cost for one week of renting the car

agency charges $230 per week

$charge = 230$

agency charges $0.25 per mile (lets set the number of miles as 'x')

$charge = 230 + 0.25x$

The total cost was 415, therefore:

$415 =230 + 0.25x\\185 = 0.25x\\x = 740$

Therefore, you traveled 740 miles

Answer: 740 miles

Hope that helps!
