Question

Kathleen 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. Slow heart rate (100 bpm) 4. Brown eyes 3 3 Blue eyes 3 What is the probability that a randomly selected baby has a fast heart rate (>100 bpm) given that the baby has brown eyes? Simplify any fractions.

Answer 1

totalGiven the probability formula

`P(x)=(n(x))/(n(T))`

Where:

x is the required outcome

T is the total number of outcome

Thus,

The Total number of outcomes is = 3 + 3 + 4 + 3= 13

The number of babies with brown eyes and fast heart rate (>100) is = 4

`\begin{gathered} n(x)\text{ = 4} \\ n(T)=\text{ 13} \\ \text{Thus } \\ P(x)\text{ = }(n(x))/(n(T))=(4)/(13) \end{gathered}`
