Question: According to the Alzheimer s Association www alz org documents custom 2011 Facts Figures Fact Shee
According to the Alzheimer’s Association (www.alz.org/documents_custom/2011_Facts_Figures_ Fact_Sheet.pdf), 3.7% of Americans with Alzheimer’s disease were younger than the age of 65 years in 2011 (which means that they were diagnosed with early onset of Alzheimer’s). Suppose that currently 3.7% of Americans with Alzheimer’s disease are younger than the age of 65 years. Suppose that two Americans with Alzheimer’s disease are selected at random. Let x denote the number in this sample of two Americans with Alzheimer’s disease who are younger than the age of 65 years. Construct the probability distribution table of x. Draw a tree diagram for this problem.
