52% of adults say chocolate chip is their favorite cookie. A community bake sale staff has prepared 350 chocolate chip cookies. If the sale attracts 650 customers and they each buy one cookie, what is the probability that there will not be enough chocolate chip cookies?

Decide whether you can use the normal distribution to approximate the binomial distribution. If so, use the normal distrubution to approximate the probability.

I tried to do this, but I am not sure what formulas to use and then plug into the calculator.
