According to a report from the Center for Studying Health System Change, 20% of Americans delay or go without medical care becau
Svet_ta [14]

Answer:

The probability no one delays or goes without medical care is 0.168;

The probability only one person delays or goes without medical care is 0.336.

Step-by-step explanation:

This problem can be modeled with a binomial random variable, with sample size n=8 and probability of success p=0.2.

The probability that <em>exactly </em>k Americans delay or go without medical care because of concerns about cost within the sample of eight individuals can be calculated as:

P(x=k) = \dbinom{n}{k} p^{k}(1-p)^{n-k}\\\\\\P(x=k) = \dbinom{8}{k} 0.2^{k} 0.8^{8-k}\\\\\\

The probability no one delays or goes without medical care (x=0) is:

P(x=0) = \dbinom{8}{0} p^{0}(1-p)^{8}=1*1*0.168=0.168\\\\\\

The probability only one person delays or goes without medical care (x=1) is

P(x=1) = \dbinom{8}{1} p^{1}(1-p)^{7}=8*0.2*0.21=0.336\\\\\\

We must find -2^4

This is 16( Note this is positive because the minus sign becomes plus due to multiplying it 4 times )
