Amazon is one of the top leading online retailers today. One of the strategies that Amazon attributes their success and profitability to is from their suggestive add-on feature during checkout, which strategically recommends complementing products based on what the customer has in their shopping cart. Thus, Amazon wanted to know what percentage of their customers actually make an add-on purchase from Amazon's recommendations. From their findings, Amazon found that 30% of their customers who make a purchase also purchase an add-on product from that feature. Assuming this is true, use the binomial distribution table to determine the probability that in a random sample of 25 customers:
1.) 5 or more will make an add-on purchase due to Amazon's feature.
2.) Less than 10 will make an add-on purchase due to Amazon's feature.
3.) 6 people will make an add-on purchase due to Amazon's feature.
