A food truck near the University of Windsor specializes in healthy sandwiches. The sandwiches are prepared fresh each morning and any unsold sandwiches are donated to a food bank. Each sandwich costs $6 to make and sells for $10. The daily number of sandwiches sold, x, has the following distribution: (shown in image) a. Fill in the missing probability in the table above b. What is the expected daily profit? (hint: find the mean of x and multiply it by profit per sandwich) c. Find the mean, variance and standard deviation of the number of daily number of sandwiches sold.
