Julie won a chance to choose an envelope from a tote in a local competition. Each envelope contains?
a certificate for a prize offered by a local retailer. The price values are normally distributed with a mean value of $ 60 and a standard deviation of $ 30. What is the probability Julie will win a prize worth more than $ 75? Please Help me!
The formula for calculating it. You just need to know the cumulative distribution than the mean + sd / 2. Http: / / en.wikipedia.org / wiki / Normal_distribution # Cumulative_distribution_function
