Problem 161E

A Web ad can be designed from four different colors, three font types, five font sizes, three images, and five text phrases. A specific design is randomly generated by the Web server when you visit the site. Let A denote the event that the design color is red, and let B denote the event that the font size is not the smallest one. Are A and B independent events? Explain why or why not.

ANSWER:

Solution:

Step 1 of 2:

Here it is given a Web ad can be designed using four different colors,three font types,five font sizes,three images and five text phrases.

Also, it is given that A denotes the event that the design color is red and the event that the font size is not the smallest one is denoted by B.

Using this we have to check whether  events A and B are independent or not.
