Question

1.If 56% of Americans say they live paycheck to paycheck find the probability that 7 randomly selected Americans say they live paycheck to paycheck. Round the final answer to 2 or 3 decimal places.

2.The following doctors were observed on staff at a local hospital.

Choose one doctor at random. Find the probabilities of the following and express your answer as a fraction or decimal rounded to 3 decimal places: Pathologist? Pediatrician? Orthopedics?

Explanation / Answer

1. Required probability = 0.567 = 0.017

2. Total doctors observed = 5 + 1 + 4 + 4 + 17 + 3 = 34

So,

P(Pathologist) = (5 + 1)/34 = 6/34 = 3/17

P(Pediatrician) = (4 + 4)/34 = 8/34 = 4/17

P(Orthopedics) = (17 + 3)/34 = 20/34 = 10/17
