Based on a recent report, the cost of healthcare is $8,086 per person in the United States. Suppose that this is the population mean and the population standard deviation is $2,500. A research firm will take a sample of 15 people to investigate the nature of their health expenditures.

What is the probability the sample mean amount of healthcare expenditure will be greater than $9,000?

1. if we have 3 babies what is the probability they’re going to be all boys? 2. if we roll 2 die at the same time what is the probability of getting less than 10 on the first roll and a 5 on the second roll 3. if we have 3 babies what is the probability their is going to be 2 girls? 4. if we have 3 babies what is the probability of having no more than 1 girl? 5. it we have 3 babies and then have another 3 babies what is the probability of us having at least 1 boy and then having all girls?
