You have a normal distribution so you need to convert it to the standard normal distribution, set up the probability statement as a mathematical expression and use the standard normal table to determine the probability. In the current problem the mean of the distribution is n × μ = 50 × $750 = $37, 500 and the standard deviation is σ × √n = $25 × √50. Harley
