Suppose you have a standard normal variable. So it\'s Gaussian with mean zero and variance 1. What is the probability that it will be negative ?
Suppose you have a standard normal variable. So it\'s Gaussian with mean zero and variance 1. What is the probability that it will be negative ?
Solution
mu=0;
std=1;
s=10000;
v=normrnd(mu,std,s,1);
n=0;
for i=1:s
if v(i)<0
n=n+1;
end
end
prob=n/s
prob =
0.4985
probability is varying between 0.49 to 0.51
