What if you wanted to calculate X>7

[@mathshelpwithmrorys8555]

Just do 1 - P(X

[@LeahRebecca]

cheers!!

You're welcome.

What if you have P(X>5)?

[@mathshelpwithmrorys8555]

Just do 1 - P(X

[@anonymoususer2756]

Or P(X

[@rebeccapagano4047]

But it doesn’t give me the right answer
For example i want P(X=49) when X is Bin (80,0.5) and it says 0.0118.. but the answer is 0.024 (0.5)^49*(0.5)^31*bin(80,49)

[@riemashanaachandragantha4655]

are you sure that's the question asked like is it x=49 or maybe greater than or less than?
