1. In recent years a new type of taxi service has evolved in more than 300 cities worldwide, where the customer is connected directly with a driver via a smartphone. The idea was first developed by Uber Technologies, which is headquartered in San Francisco, California. It uses the Uber mobile app, which allows customers with a smartphone to submit a trip request which is then routed to a Uber driver who picks up the customer and takes the customer to the desired location. No cash is involved, the payment for the transaction is handled via a digital payment. Suppose the weekly income of Uber drivers follows the normal probability distribution with a mean of $1,000 and a standard deviation of $100.(1)What is the probability of selecting a driver whose income is

1) Between $790 and $1,000? (30 points)

2) Less than $790? (30 points)

What is the area under this normal curve between $840 and $1,200?
