Algebra.Com's Answer #502007 by Fombitz(32388)![]() ![]() You can put this solution on YOUR website! Probabilities are outcomes that you're interested in divided by total outcomes. \n" ); document.write( "Probabilities are always at least zero and at most 1. \n" ); document.write( "Albert rolled the cube \n" ); document.write( "a) P(2)= \n" ); document.write( "b) P(1 or 5)=P(1)+P(5)= \n" ); document.write( "c) P(not a 5) means P(everything but a 5)= \n" ); document.write( "You could also get it by summing all the probabilities of the other numbers, \n" ); document.write( "P(not a 5)=P(1)+P(2)+P(3)+P(4)+P(6)= \n" ); document.write( "d) P(6)=6/66= |
