If you’re good with probability math 30 please help with questions 33 and 35! real answers only
drek231 [11]

Answer:  33) b      34) a        35) none

<u>Step-by-step explanation:</u>

33)

Filling in the Venn Diagram (from Left to right, including outside of circles):

T only           = 13

(T ∩ F)only   =  6

F only           = 21

(T ∩ D) only  =  3

T ∩ F ∩ D     =  5

(F ∩ D) only  =  8

D only           = 15

<u>(T ∪ F ∪ D)'    = 11   </u>

   TOTAL      = 82

P(D'\cap F) = \dfrac{6+21}{13+6+21+3+5+8+15+11}\quad =\large\boxed{\dfrac{27}{82}}

34)

Red  = 26

Face  = 12

Red ∩ Face = 6

Total cards = 52

R ∪ F = R + F - (R ∩ F)

        = 26 + 12 - 6

        = 32

P(R\cup F)=\dfrac{R\cup F}{Total}\quad =\dfrac{32}{52}\quad \rightarrow \quad \large\boxed{\dfrac{8}{13}}

35) Note that the total is 34 + 17 + 8 + 3 + 9 + 4 + 5 = 80

<em>I think the teacher made an error, if so, then the answer is "d".</em>

P(C) = \dfrac{34+17+3+9}{Total} =\dfrac{53}{80}\quad \bigg(not\ \dfrac{34}{75}\bigg)\qquad \text{This is False.}\\\\\\P(S\cap T)=\dfrac{9+0}{Total}=\dfrac{9}{80}\quad \bigg(not\ \dfrac{12}{75}\bigg)\qquad \text{This is False.}\\\\\\\\P(C\cup T)\cup S = \dfrac{17+9+3+4}{Total}= \dfrac{33}{80}\quad \bigg(not\ \dfrac{38}{75}\bigg)\qquad \text{This is False.}\\\\\\P(C\cup T)\cap S'=\dfrac{34+17+8}{Total}=\dfrac{59}{80}\quad \bigg(not\ \dfrac{59}{75}\bigg)\quad \text{This is False.}

Shelby is an entrepreneur who has decided to open a small advertising firm. She rents office space at a cost of $25,000 per year
mestny [16]

Answer:

$ 125,000

Step-by-step explanation:

Given,

The amount of rent = $ 25,000,

The salary of assistant = $ 30, 000

Expenses = $ 20,000,

Also, her best alternative is to work elsewhere and to earn a salary of $50,000 per year.

Thus, the investment in the firm = 25000 + 30000 + 20000 + 50000

= $ 125,000,

Now, if she earns zero economic profit,

Then her revenue = investment

= $ 125,000
