I'm trying to figure out the steps needed to solve this problem:
A survey of adults ages $18-24$ found that $38\%$ get no news on an average day. You randomly select $250$ adults ages $18-24$ and ask them if they get news on an average day.
Find the probability that at least $113$ people say they get no news on an average day.
For this, I am finding $np$, $npq$, and then adding $.5$ to find the $z$-score. It never comes out right.
Find probability that fewer than $93$ people say they got new news on an average day.
