A study was performed to assess the feasibility of a national random digit dialing cellular phone survey among young adults age 18-34. It was reported that 3.2% of respondents were eligible to participate and that 55% of eligible respondents agreed to participate. Suppose 1000 potential participants are contacted to participate in this survey. What is the approximate probability that at least 12 of the 1000 participants will be eligible and agree to participate?
