Normal Distribution Probability Finder

Trying to use normal distribution with mean = 0 and variance = 1 to find the prob(X>-2.125)

How would I go about doing this?

Answer 1

[Massimo Zanetti]

pp = makedist('Normal','mu',0,'sigma',1);
yourP = 1-cdf(pp,-2.125)

Answer 2

>> norminv(0.1,-2.125)
ans =
 -3.4066
>>

if have Stat Toolbox.

Right answer, wrong question (and a typo, to boot)... :(

>> 1-normcdf(-2.125)
ans =
  0.9832
>>

[Massimo Zanetti]

Negative probability seems quite wrong.....

Think? :) Misread query, sorry...
