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?

Answer:

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

makvit [3.9K]

Answer:

milk_produced = float(input("Enter the total amount of milk produced in the morning: "))

liter_cost = float(input("Enter the cost of producing one liter of milk: "))

carton_profit = float(input("Enter the profit on each carton of milk: "))

carton_needed = round(milk_produced / 3.78)

cost = milk_produced * liter_cost

profit = carton_profit * carton_needed

print("The number of milk cartons needed to hold milk is " + str(carton_needed))

print("The cost of producing milk is " + str(cost))

print("The profit for producing milk is " + str(profit))

Explanation:

*The code is in Python.

Ask the user to enter milk_produced, liter_cost and carton_profit

Calculate the number of milk cartons needed, divide the milk_produced by the capacity (3.78) of a cartoon and round the result

Calculate the cost, multiply the milk_produced by liter_cost

Calculate the profit, multiply the carton_profit by carton_needed

Print the results
