You can put this solution on YOUR website!
(a)How many of the resorts provided only refrigerators in the guest rooms?
9
(b)How many of the resorts provided exactly one of the features?
9+8+3
= 20
(c)How many of the resorts provided at least one of the features?
9+8+3+10+7+12+8
= 57
(d)How many of the resorts provided exactly two of the features?
10+8+12
= 30
(e)How many of the resorts provided none of the features?
75-9-8-3-10-7-12-8
= 18
I will leave the Venn diagram to you
