Approximating Probabilities of Workers that Use Public Transport

Suppose 5.9% of certain population use public transportation to get to work. You randomly select 380 workers and ask them if they use public transportation to get to work. Use the normal distribution to approximate the following probabilities.

1) find the probability that exactly 25 workers will say yes.

2) at least 25 workers will say yes.

3) fewer than 25 workers will say yes.
