Explanation / Answer

It is given that in 2012, 8.8% people older adults in the Unted States had dementia. Hence, the probability value is 0.088. The given situation is binomial probability, where sucess is the probability of choosing x old persons having dementia from total N persons. The probability distribution is given as

P(x, N, p) = NCx px (1-p)N-x

Hence, for given problem N=7, x=2, p=0.088. Thus required probability is

P(2, 7, 0.088) = 21 * 0.0882 * 0.9125 =0.1026
