3). Two balls are selected at random from a bag containing 4 white and 2 black balls. Find the probability that:
\n" ); document.write( "i) Both are white.
\n" ); document.write( "P(both white) = 4C2/6c2) = 6/15 = 2/5
\n" ); document.write( "------------------------------------------------
\n" ); document.write( "ii) Both are of the same colour.
\n" ); document.write( "P(both white or both black) = P(both white) + P(both black)
\n" ); document.write( "= 2/5 + 2C2/6C2 = 2/5 + 1/15 = (6+1)/15 = 7/15
\n" ); document.write( "------------------------------------------------\r
\n" ); document.write( "\n" ); document.write( "iii) Both are of the different Colour.?
\n" ); document.write( "P(both white) + P(both black) + P(different color) = 1
\n" ); document.write( "P(different color = 1 - [P(both white) + P(both black)] = 1-7/15 = 8/15
