The arrival of customers during randomly chosen 10-min intervals at a drive-in facility specializing in photo developmentand film sales has been found to follow the probability distribution in the following table. Calculate the expected numberof arrivals for 10-min intervals and the standard deviation of the arrivals. Use the table below to compute for thefollowing:Arrivals of Customers at a Photo-processing Facility during 10-min Intervals...Number of arrivals, X1234Probability, P(X)0.150.250.250.200.100.05PromptsExpected number of arrivals for 10-min intervalsVariance of arrivals for 10-min intervalsStandard deviation of arrivals for 10-min intervals
