If 'poissoncdf(147,160)' includes values up to and including 160, then wouldn't the '1 - poissoncdf(147,200)' exclude 200 from the calculation? Which would make the results actually be for greater than or equal to 201?
Hey Robert, Yes! If you want x ≥ 201 and have the average of 147 then you can use the TI-84+ to calculate 1 - poissoncdf(147, 200). Using this function will take 100% of possible outcomes (aka =1 for probability) and "cut off" the cumulative probabilities for 0 to 200 leaving you 201 and more.
1.3831E-5 is in scientific notation. This means we need to divide 1.3831 by 100000 to see the decimal version of the value 1.3831E-5 = 0.000013831 (this is a very small probability)
you are better than my teacher LMAO, thank u
OMG this video is a life saver, not to mention time saver!! THank you so much!!!
You are very welcome. I'm glad it helped
me when the professor allows us to use scientific calculators for the exams
Very straightforward and helpful
Thank you, this was very helpful!
Thank you!! you are smart
Thank you for the compliment.

Thank you so much! :)
3:49 sorry, but where does it say the incredibly small amount 0.000001? Where does it show that #?
