document.write( "Question 921303: A nonprofit organization conducted a survey of 2100 metropolitan-area teachers regarding their beliefs about educational problems. The following data were obtained:
\n" ); document.write( "870 said that lack of parental support is a problem.
\n" ); document.write( "860 said that abused or neglected children are problems.
\n" ); document.write( "680 said that malnutrition or students in poor health is a problem.
\n" ); document.write( "120 said that lack of parental support and abused or neglected children are problems.
\n" ); document.write( "90 said that lack of parental support and malnutrition or poor health are problems.
\n" ); document.write( "130 said that abused or neglected children and malnutrition or poor health are problems.
\n" ); document.write( "30 said that lack of parental support, abuse or neglect, and malnutrition or poor health are problems.
\n" ); document.write( "What is the probability that a teacher selected at random from this group said that lack of parental support is the only problem hampering a student's schooling? Hint: Draw a Venn diagram. (Round your answer to three decimal places.)
\n" ); document.write( "I have drawn the venn diagram but I'm still not sure. I thought to subtract the 120,130,90,30 from 870 then divide that by 2100 but that's wrong. So I'm not sure what to do.
