A baseket contains 6 blue,2 red,4 green and 3 yellow balls
\n" ); document.write( "1. if 2 balls are picked at random, what is the probability that either both are
\n" ); document.write( "green or both are yellow?
\n" ); document.write( "---
\n" ); document.write( "P(2green OR 2yellow) = P(2green) + P(2yellow)
\n" ); document.write( "= [4C2/15C2]+[3C2/15C2] = [6+3]/105 = 9/105
\n" ); document.write( "-----------------------------------------------
\n" ); document.write( "2. If 5 balls are picked at random, what is the probability that at least one is blue.
\n" ); document.write( "P(at least one blue) = 1-P(none blue)
\n" ); document.write( "= 1 - [9C5/15C5]
\n" ); document.write( "= 1 - 0.0420
\n" ); document.write( "= 0.9580
\n" ); document.write( "---------------------------------------------------
\n" ); document.write( "3. If 2 balls are picked at random, what is the probability that both are blue?
\n" ); document.write( "P(2blue) = [6C2/15C2]
\n" ); document.write( "-------------------------------
\n" ); document.write( "4. If 4 balls are picked at random what is the probability that 2 are red and 2 are green
\n" ); document.write( "P(2red AND 2green) = P(2green|2red)*P(2red) = [3C2/13C2][2C2/15C2]
\n" ); document.write( "--------------------------------------
\n" ); document.write( "5.if 3 balls are picked at random what is the probability that none is yellow
\n" ); document.write( "P(no yellow) = 12C3/15C3
\n" ); document.write( "==============================
