Solve problems involving normal random variables:
The height of a certain species of wild cat is normally distributed with mean 28 cm and standard deviation 3.6 cm. What is the probability that a cat from this species is at least 26 cm tall?

I don't get how to do poisson random variables

Why do you think it is "Poisson" when you told us it was "normally distributed"?

Calculate the Z-score. [math]\dfrac{26-28}{3.6} = [/math] what? What's the Normal Probability for being greater than that value?

Don't forget, it's more than 1/2. You tell me why this is so.

that was a mistake lol, i had a brain fart

...and your results?

"I think"? What kind of an answer is that?

Did you miss my hint? "Don't forget, it's more than 1/2. You tell me why this is so."

Hint: Draw a diagram and shade in the area of interest.
