Assignment 2

We assume :
-have computers = 221 = C
-have programming books = 159 = B
-have both = 87 = T

Answers :

c + 87 = 221
c = 221-87 = 134

B + 87 = 159
B = 159-87 = 72

T = C + B +87
T = 134 + 72 + 87
T = 293

Find percentage (%) of student who :

a) have at least one computers and programming books
= C + B
= ((C/293) * 100) + ((B/293) * 100)
= ((134/293) * 100) + ((72/293) * 100)
= 45.73% + 24.57%
= 70.3%

b) have only computers
=((134/293) * 100)
=45.73%

c) have only programming books
=((72/293) * 100)
=24.57%

d) have both computers and programming books
have both we assume as T
T = 293
T/100 = 293/100
T = 29.3
