In a certain residential suburb, 60% of all households get Internet service from the local cable company, 80% get television ser
Serggg [28]

Answer:

a) 0.900

b) 0.400

Step-by-step explanation:

Let I = households getting internet

T = households getting television

Then I = 60%

and T = 80%

I\cap T = 50\% (Households that get both services)

a) Households getting at least one service, I\cup T = I + T - I\cap T= 60+80-50 =90\%=0.900

b) Those getting internet only = I - I\cap T = 60 - 50 = 10\% = 0.1

Those getting television only = T - I\cap T = 80- 50=30\%=0.3

Probability of getting exactly one service = 0.1 + 0.3 = 0.400
