Question

A bag contains 36 balls , of which k are red ,2k are white ,3k are blue. A ball is drawn randomly .find theprobability of drawing white or blue ball

Answer 1

hey as k =red balls and 2k = white balls and 3k =blue balls
there are a total of 6k balls =36
$k = 36 \div 6$
$k = 6$
so the probability of white or blue ball to be chosen =
$(2k + 3k ) \div 36$
$30 \div 36$
$5 \div 6$
hope this might help you
