Scientists attach tags and electronic tracking devices to monitor animal populations. Marine biologists wanted to estimate the Great White Shark population in Southern California. They tagged 25 sharks during one week in May. A few months later, they observed 35 sharks in the same location and 10 of them had tags. Estimate the shark population. Do you think that this is a good random sample and will the estimate will be fairly accurate? Explain

Exclude leap years from the following calculations. (a) compute the probability that a randomly selected person does not have a birthday on october 4. (type an integer or a decimal rounded to three decimal places as needed.) (b) compute the probability that a randomly selected person does not have a birthday on the 1st day of a month. (type an integer or a decimal rounded to three decimal places as needed.) (c) compute the probability that a randomly selected person does not have a birthday on the 30th day of a month. (type an integer or a decimal rounded to three decimal places as needed.) (d) compute the probability that a randomly selected person was not born in january. (type an integer or a decimal rounded to three decimal places as needed.)
