Scenario 4 : Finding an area under a curve and above the x-axis
� Apart from using the function MATH 9 , you can sketch the curve and use the function 2nd trace 7 , and then set the lower limits and the upper limits .
Scenario 5 : Finding probabilities in a Binomial distribution , in the form P ( X � c) ,
P ( X � c) or P ( X � c)
� You need to change the probability to the form P ( X � C ) , and then use the function 2nd vars B to choose binomcdf .
