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
