1. The Tholians are trying to capture Enterprise by creating a 'space web'

The width of the square gaps or holes in the web is normally distributed with a mean width of 400 feet and a standard deviation of 16 feet. Enterprise requires a gap of at least 422 feet to escape.

A.) What is the probability that a gap will be 420 feet or wider?

B.)If there are 10,000 gaps in a web, approximately how many will Enterprise be able to pass through?
