Last year, the personal best high jumps of track athletes in a nearby state were normally distributed with a mean of 229 cm and a standard deviation of 19 cm. What is the probability that a randomly selected high jumper has a person best between 229 and 248 cm?

According to a poll conducted in a company, 47% of the employees regularly use the internet while at work. You conduct a similar survey at your mother's office where there are 250 respondents. What is the probability you find between 102 and 117.5 employees who use the internet while at work?

I have no idea how to solve either one of these problems, could someone please show me the steps?
