Question 417569
According to the Center for Disease Control, 41.5% of babies born in the U.S. in 2004 were still being breastfed at 6 months of age. 
------------------------------------------
If 4 children who were born in the U.S. in 2004 are randomly selected, what is the probability that none of them were breastfed for at least 6 months.
Ans: (1-0.415)^4 = 0.585^4 = 0.1171
