Question 909673: using this information, The product (Colgate Total Toothpaste) was launched in the United States in January of 1998 using commercials that were designed from the more successful ideas of the focus group tests. Total was introduced with a $100 million advertising campaign. Ten months later, 21% of all United States households had purchased Total for the first time. During this same time period, 43% of those who initially tried Total purchased it again: What Is The Percentage of U.S. Households Who Purchased Total At Least Twice In The First 10 Months Of Its Release? I am completely lost on where to start with this question. I wasn't sure if I was supposed to used the binomial probability distribution rule or not.
