A bag contains 3 red beads and 5 yellow beads. One bead is removed at random then replaced. This is done three times in total.
\n" ); document.write( "-------------------------------
\n" ); document.write( "Find the probability that:
\n" ); document.write( "a) Each bead is red::(3/8)^3
\n" ); document.write( "-------
\n" ); document.write( "b)Exactly two beads are red and one bead is yellow
\n" ); document.write( ":::3C2(3/8)(5/8)^2 = 0.4395
\n" ); document.write( "================================
\n" ); document.write( "c)At least one bead is red::
\n" ); document.write( "1-P(all yellow) = 1-(5/8)^3
\n" ); document.write( "================================
