Question

A study of 400 interior designers' opinions with respect to the most desirable primary color for executive offices showed the following: Primary Color Number of Opinions Red 92 Orange 86 Yellow 46 Green 91 Blue 37 Indigo 46 Violet 2 What is the probability that a designer does NOT prefer red?

Answer 1

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 = $400-92=308$

Now, the probability that a designer does NOT prefer red is given by :-

$\dfrac{\text{Number designers do not prefer red}}{\text{Total designers}}\\\\=\dfrac{308}{400}=0.77$

Hence, the  probability that a designer does NOT prefer red = 0.77
