0.8 is greater because it is a positive number..
Probablity=desiredoutcomes/totalpossibleoutcomes
see which ones fit
dimes and quarters are over 9 cents
there are 11+3 or 14 of them
total outcomes=12+9+11+3=35
probablity=14/35=2/5
probablity is 2/5
Technically it's 2x subtracted by 1 and 8 more than that so:
(2x-1)+8
