Several products are manufactured within the hospitality sector. Let's focus on the hourly production of forks destined for high quality restaurants.

Assuming this process to be normally distributed with a mean equal to 100 and a standard deviation equal to 7.24, what is the probability that the number of forks produced hourly is:

(a) less than or equal to 100 per hour? [2 marks]

(b) more than 109 per hour? [3 marks]

(c) between 100 and 109 per hour? [3 marks]
