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.
