Grab Bag
Julie has won a chance to pick an envelop from a grab bag in a local contest. Each envelope contains?
a certificate for a prize donated by a local retailer. The values of the prizes are normally distributed with a mean value of $60 and a standard deviation of $30. What is the probability that Julie will win a prize worth more than $75?
Please Help me!!
Here is the formula to compute it. You just need to know the cumulative distribution greater than the mean + sd/2.
