The probability that a person has an Internet connection at home is 34%. The probability that they have access to the Internet at work is 40%. The probability that a person who has access to the Internet at work also has access at home is 55%
What is the probability that a person with an Internet connection at home also has one at work?
H = Internet at home
W = Internet at work
P(H) = 0.34, P(W) = 0.40, P(H/W) = 0.55.
Hence, P(H ? W)=P(H/W) ? P(W) = (0.55 )(0.40 ) = 0.22 and P(W/H) = P(W ? H)/P(H) = 0.22/0.34 = 0.647.
