Question

Laura is a pediatrics nurse who conducts the first neonatal exam on newborn patients. She makes note of the newborns' height, weight, eye color, and heart rate, among other things. Brown eyes Blue eyes 4 5 Slow heart rate (100 bpm) 3 2 What is the probability that a randomly selected baby has a fast heart rate (>100 bpm) or has brown eyes? Simplify any fractions.

Answer 1

Given a table of the newborns:

The total number of newborns = 4 + 5 + 3 + 2 = 14

The probability of selected baby has a fast heart rate > 100 bpm = 5/14

The probability of selected baby has brown eyes = 7/14

So, the probability of a randomly selected baby has a fast heart rate (>100 bpm) or has brown eyes =
