Hi there I need help with these questions

A survey of athletes at a high school is conducted, and the following facts are discovered: 41% of the athletes are football players, 47% are basketball players, and 22% of the athletes play both football and basketball. An athlete is chosen at random from the high school: what is the probability that the athlete is either a football player or a basketball player? Probability- % (Please enter your answer as a percent) Show Intro/Instructions Use the spinner below to find the probability of getting the following after 1 spin. /1 2/1] (or1) P(number > 5)- (Round to 4 decimal places) 12 10 P(even) (Round to 4 decimal places) 12 P(4 or 7)- (Round to 4 decimal places) Answer exactly or round to 4 decimal places. You toss a fair coin 4 times. What is the probability that a) you get all Tails? Preview b) you get at least one Head? When doing blood testing for a viral infection, the procedure can be made more efficient and less expensive by combining partial samples of different blood specimens. If samples from four people are combined and the mixture tests negative, we know that all four individual samples are negative. Find the probability of a positive result for four samples combined into one mixture, assuming the probability of an individual blood sample testing positive for the virus is 0.03. Round the answer to four decimal place accuracy. In a large population, 66% of the people have been vaccinated. If 3 people are randomly selected, what is the probability that AT LEAST ONE of them has been vaccinated? Give your answer as a decimal to 4 places. Enter your answer a Use the following probabilities to answer the question. Round to 4 decimal places. P(A) = 0.74, P(B) = 0.21, P(A and B) = 0.05 P(B | A)= Jacob buys a bag of cookies that contains 8 chocolate chip cookies, 5 peanut butter cookies, 8 sugar cookies and 8 oatmeal raisin cookies. What is the probability that Jacob randomly selects a sugar cookie from the bag, eats it, then randomly selects another sugar cookie? (Round your answer to 4 decimal places.) Malik buys a bag of cookies that contains 6 chocolate chip cookies, 8 peanut butter cookies, 5 sugar cookies and 7 oatmeal cookies. What is the probability that Malik randomly selects a chocolate chip cookie from the bag. eats it, then randomly selects a sugar cookie? Probability = (Round your answer to 4 decimal places.) TIP
