Answer:
Kindly check attached picture ; 37.5%
Step-by-step explanation:
Let:
S = number of science fiction movie viewers
H = number of horror movie viewers
A = number of adventure movie viewers
From the information given :
n(SnHnA) = 5
n(SnH) only = 15 - 5 = 10
n(SnA) only = 25 - 5 = 20
n(AnH) only = 5 - 5 = 0
n(S) only = 40 - (10+5+20) = 5
n(H) only = 40 - (10+5+0) = 25
n(A) only = 50 - (5 + 20 + 0) = 25
2.) % of science fiction movie to horror movie fans
Total Science fiction movie fans = n(S) = 40
Science fiction and Horror movie fans = n(SnH) = 15
[n(SnH) / n(S)] * 100%
(15 / 40) * 100%
0.375 * 100%
= 37.5%
