Answer: 0.77
Step-by-step explanation:
Given : The number of interior designers = 400
The number of interior designers prefer red = 92
The number of interior designers do not prefer red = [tex]400-92=308[/tex]
Now, the probability that a designer does NOT prefer red is given by :-
[tex]\dfrac{\text{Number designers do not prefer red}}{\text{Total designers}}\\\\=\dfrac{308}{400}=0.77[/tex]
Hence, the probability that a designer does NOT prefer red = 0.77
