T-84 Binomcdf and Normalcdf help!

Recommended Posts

Hey Guys!

So the Math SL exam is tomorrow, and I can't find the answer to my question.

 

When we want to use normalcdf/ binomcdf, whats the difference if the question asks us to find the probability "less than" and "less than or equal to"

In continuous data, whats the difference in the inputs?

Hi. There is no difference between less than vs less than and equal to in NORMALCDF.
In binomcdf, you want P(X <= 5) you do binomcdf (n, p, 5), if you want P(X < 10) you do binomcdf (n, p, 9) such that you add up to P(X = 9) and stop.

Good luck!

What if the data is continuous for binom?
