Perform a close reading of the following paragraph, and solve Questions 1-3, using the BUCKS annotations:

The retirement of baby boomer nurses will impact the nursing shortage, forcing hospitals to turn to new graduates to staff their beds and provide patient care. New nursing graduates are now the largest source of registered nurses available for recruitment in the nation, facing difficult psychological and intellectual challenges as they adapt to their new careers. Graduates face new emotional stressors, such as navigating a new environment and working overnight shifts, which contribute to increased turnover in the first year. New graduate nurses often lack the skills to transition quickly to the bedside role. They also are more likely to resign than experienced hires; 75% of new graduate nurses leave their job within the first year, with estimated turnover cost per nurse of $22,420- $77,200 (Nursing Executive Center, 2005). In an effort to combat this high turnover, Nursing Residency Programs (NRPs) were designed to establish a smooth transition from student life into professional life.

1. Suppose a hospital offers better perks and pay, and so is able to attract more experienced nurses, whose probability of leaving in the first year is lower - let's say that typically only 50% leave the first year. In this year, the hospital hired 10 new nurses. What is the probability of getting more than 6 nurses leaving after one year, which can be written as P(X > 6)?

n =
