Question: SWITCHING INTERNET SERVICE PROVIDERS (ISPS) According to a survey conducted in 2004 of 1000 American adults with Internet access, one in four households plans to switch ISPs in the next 6 months. Of those who plan to switch, 1% of the households are likely to switch to a satellite connection, 27% to digital subscriber line (DSL), 28% to cable modem, 35% to dial-up modem, and 9% don't know what kind of service provider they will switch to.
a. What is the probability that a randomly selected survey participant who was planning to switch ISPs will switch to a dial-up modem connection?
b. What is the probability that a randomly selected survey participant will upgrade to high-speed service (satellite, DSL, or cable)?
