Use the normal distribution to approximate the desired probability.

A coin is tossed 20 times. Aperson, who claims to have extrasensory perception, is asked to predict the outcome of each flip in advanced. She predicts correctli on 16 tosses. What is the probability of being correct 16 more times by guessing? Does this probability seem to verify her claim?

16/20=0.8 and yes becauase it greater than 5% or am I completely wrong?

Is that correct? This freaks me out to where I feel like I can't even add. Someone help PLEASE....
