1. In shipment containing 10 TV sets, 2 are defective. Two TV sets are taken for inspection in succession without replacement. What is the probability that
\n" ); document.write( "a. A defective TV sets shall be taken on the first draw?
\n" ); document.write( "2/10
\n" ); document.write( "----------------
\n" ); document.write( "b. A non-defective shall be taken on the first and a non-defective on the second?
\n" ); document.write( "(8/10)(7/9) because of \"without replacement\" these are dependent events.
\n" ); document.write( "----------------
\n" ); document.write( "c. A non-defective on the second given that it is a non-defective on the first?
\n" ); document.write( "P(N|N) = (7/9)
\n" ); document.write( "----------------
\n" ); document.write( "------------------
\n" ); document.write( "2. Two balls are drawn in succession with replacement from a box containing 5 red, 4 blue, and 2 yellow balls. If the first ball drawn is red, then what is the probability that the second ball is drawn
\n" ); document.write( "COMMENT: Because of \"with replacement\" it doesn't matter what happened on the
\n" ); document.write( "first draw.
\n" ); document.write( "a. P(Red)=5/11
\n" ); document.write( "b. P(Blue)=4/11
\n" ); document.write( "c. P(Yellow)=2/11
\n" ); document.write( "----------------
