Can someone please help me

Question

For a standard normal distribution, what’s the probability of getting a number less than zero?
75%
63%
50%
43%

34%

 

Can someone please help me. I am not sure how I am supposed to figure this out since I was not given any numbers. The only thing I can honestly say is I would guess 50%.

Answer 1

In Standard Normal Distribution (Z scores on horizontal axis), the peak is at Z=0, representing 50% of the area under the curve.

 

Good guess, Lydia!
