D. a liberal arts degree, a computer engineering degree, and a nursing degree? There are ____ four-year colleges and universities that offer a liberal arts degree, a computer engineering degree, and a nursing degree. Enter your answer in each of the answer boxes.
Answer:
a)
To give the required terms
Consider,
Number of colleges or universities who offered at least one degree = arts + computer engineering + nursing - arts and computer engineering - arts and nursing - computer engineering and nursing + all three
substitute the given values in above formula
= 255 + 110 + 481 - 30 - 211 - 86 + 25
Number of colleges or universities who offered at least one degree = 544
Number of colleges or universities surveyed = Number of colleges or universities who offered + Number of colleges or universities who don't offered
substitute the given values
= 544 + 33
Number of colleges or universities surveyed = 577
Of the four year colleges and universities surveyed, 544 offered.
b)
Here arts and nursing but not computer engineering = arts and nursing - all three
substitute given values
= 211 - 25
The arts and nursing but not computer engineering = 186
c)
Only computer engineering = computer engineering - arts and computer engineering - nursing and computer engineering + all three
substitute given values
= 110 - 30 - 86 + 25
Only computer engineering = 19
d)
Here arts, nursing and computer engineering together = 25
