Algebra.Com's Answer #238875 by jrfrunner(365) You can put this solution on YOUR website! Fundamentally, probability is straight foward \n" ); document.write( "--- \n" ); document.write( "Probability = (Number of a certain type of events)/(total number of events) \n" ); document.write( "The difficult part is sometimes enumarating the number in each part of that fraction. \n" ); document.write( "--- \n" ); document.write( "In your case is not bad at all to enumarate the events. \n" ); document.write( "probability of obtaining a number which is odd on a fair die, there are a total of 6 events {1,2,3,4,5,6} and there are 3 odd events {1,3,5} \n" ); document.write( "-- \n" ); document.write( "so P(a number which is odd)=Number of odd events/total events = 3/6=1/2 \n" ); document.write( " |
