please guys help me ... You work for an insurance company. 80% of your company’s staff is sales force and 70% of your company’s sales force is male. In your company as a whole, 60% of the staff is male. a) Create the Venn Diagram for this data. (Hints: Draw two circles, one represents “male” and the other represents “on the sale force”) b. What portion of your company’s staff is male AND on the sales force? c. What portion of your company’s staff is female AND on the sales force? @terenzreignz

Let's draw a Venn... |dw:1376524355754:dw|

terenzreignz (terenzreignz):

As per part (a) of your problem.

OpenStudy (anonymous):

ok

terenzreignz (terenzreignz):

You usually go from middle out. So, what goes here?|dw:1376524454551:dw|

terenzreignz (terenzreignz):

Meaning, what percent is Male and Sales force?

OpenStudy (anonymous):

dont reali have any idea about this one.:-)

terenzreignz (terenzreignz):

80% are sales force, and 70% *of the sales force* are men. So that makes how many percent of the work force total?

OpenStudy (anonymous):

that makes 100 %

OpenStudy (anonymous):

total

terenzreignz (terenzreignz):

Hardly. :P

OpenStudy (anonymous):

lol

terenzreignz (terenzreignz):

How did you get 100%?

OpenStudy (anonymous):

ok 80%

OpenStudy (anonymous):

since 80 percent are the sales force

terenzreignz (terenzreignz):

80% are sales force, but are all of them male?

OpenStudy (anonymous):

no jjux 70 percent are

terenzreignz (terenzreignz):

70% of what?

OpenStudy (anonymous):

of men

terenzreignz (terenzreignz):

70% of men are in the Sales Force?

OpenStudy (anonymous):

yes

terenzreignz (terenzreignz):

Then no :P

OpenStudy (anonymous):

oh really..then please tell me

terenzreignz (terenzreignz):

80% are sales force, and of these sales force, 70% are men. So how many percent of the total labour force (everyone in the company) are both male and part of the sales force?

OpenStudy (anonymous):

80 +70

OpenStudy (anonymous):

150??

terenzreignz (terenzreignz):

No. Wrong operation :P

OpenStudy (anonymous):

oh lol.

terenzreignz (terenzreignz):

Fix it.

OpenStudy (anonymous):

erm i know that if 80% of the company's staff is sales force and out of that percentage 70 % are males then its only 10% out of the 80% that may be female or??

terenzreignz (terenzreignz):

Yeah, sure, so what exactly does 70% OUT OF the 80% mean?

OpenStudy (anonymous):

70 divided by 80 times 100?

terenzreignz (terenzreignz):

Are you guessing? lol

OpenStudy (anonymous):

yeah i am

terenzreignz (terenzreignz):

Well, that's not really healthy, now is it? :P

OpenStudy (anonymous):

lol.i know but you know i just dont know how to figure that out..okay maybe if u begin i would be able to follow..how about that?

terenzreignz (terenzreignz):

<shrugs> 80% of the labour force are sales force 70% OF THE SALES FORCE are men. Then, those of the sales force which are also men would be \[\Large 70\% \times 80\% = 0.7\times0.8 =0.56 = 56\%\] -.-

OpenStudy (anonymous):

aww..kk let go on ..lol

terenzreignz (terenzreignz):

|dw:1376525954752:dw|

OpenStudy (anonymous):

terenzreignz (terenzreignz):
