Explanation / Answer

Solution:

Let S be the set of people with sales experience

C be the set of people with college degree

R be the set of people with real estate license

So n(S) = 74   

n(C) = 42

n(R)=42

n(S ? C) = 31

n(S ? R) = 28

n(C ? R)= 25

n(S ? C ? R)=19

n(S ? C ? R)' = 27

(a) Total applicants :

Total applicants = n(S ? C ? R)' + n(S? C ? R) n(S? C ? R)

= n(S)+n(C)+n(R) - n(S ? C) - n(S ? R) - n(C ? R) + n(S ? C ? R )

= 74+42+42-31-28-25+19= 93

(b)  Total applicants did not have sales experience:

Total applicants did not have sales experience

= n(S ? C ? R)' + n(S? C ? R) = 27+93 = 120

No of applicants not having sales experience = n(S)' =

(c) Sales experience and a college degree, but not a real estate license:

Sales experience and a college degree, but not a real estate license=11

(d) real estate license:

real estate license=8
