The “sandwich generation” is defined as adults who are financially supporting their children while providing care for their aging parents. The number of adults in this category has increased recently with higher unemployment rates, especially for young adults. Financial burdens carried by this generation can have major implications on their retirement plans. A 2012 study from the Pew Research Center reported that 15% of adults aged 40– 59 belong to the sandwich generation. A random sample of 135 adults from this age group was selected.

a. What is the probability that 16 or more adults from this sample belong to the sandwich generation?

b. What is the probability that 24 or more adults from this sample belong to the sandwich generation?

c. What is the probability that between 14 and 25 adults from this sample belong to the sandwich generation?
