Given that a computer required service, what is the probability that it was a laptop? Given that the computer required service, the probability that it was a laptop is nothing?

Complete Question:

A campus bookstore sells both types and in the last semester sold 56% laptops and 44% desktops. Reliability rates for the two types of machines are quite different, however. In the first year, 5% of desktops require service, while 15% of laptops have problems requiring service.

Given that a computer required service, what is the probability that it was a laptop?

Probability = 0.084

Explanation:

Given

Laptops = 56%

Desktop = 44%

Service Required (Laptop) = 15%

Service Required (Desktop) = 5%

Required

Determine the probability that a selected computer is a laptop and it requires service.

The question tests our knowledge of probabilities using "and" condition.

What the question requires is that, we calculate the probability of selecting a LAPTOP that REQUIRES SERVICE

Note the capitalised words.

This will be calculated as follows:

Probability = P(Laptop) and P(Service Required (Laptop))

[Substitute values for P(Laptop) and P(Service Required (Laptop))]

Probability = 56% * 15%

[Convert to decimal]

Probability = 0.56 * 0.15

Probability = 0.084

answer is:

a). backstage view

explanation:

backstage view is the area where files and data about them is managed— creating, saving, printing, sending to others, inspecting for hidden metadata or personal information, and setting options. so in this way we can add many things to our document swiftly.

i hope you get the idea.
