And where is the graph? I'll change my answer.
Not a 5 dollar just means a 10 dollar
probblity=desired outcomes/total possible outcomes
desired=number of 10 dollar notes or 30
total possible=10+30 or 40
the probablity is 30/40 or 3/4 or 75% that you do not select a 5 dollar note
Start at -4 and go over to the right 6. - is left and +is right. the answer is 2.
