A survey showed that 81% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 20 adults are randomly selected, find the probability that no more than 1 of them need correction for their eyesight. Is 1 a significantly low number of adults requiring eyesight correction? The probability that no more than 1 of the 20 adults require eyesight correction is (Round to three decimal places as needed.)

A person with a cough is a persona non grata on airplanes, elevators, or at the theater. In theaters especially, the irritation level rises with each muffled explosion. According to Dr. Brian Carlin, a Pittsburgh pulmonologist, in any large audience you'll hear about 14 coughs per minute. Find the probability of at least five coughs (in a large auditorium) in a 27-second period. (Use 4 decimal places.)

The probability that a certain type of sea turtle hatching survives until adulthood is assumed to be 1 out of 1,877.  If 980 hatchlings incubate in a certain nesting area, calculate the probability that at least 3 survive to adulthood. Use three decimal place accuracy.

According to a study, the probability that an individual will cover his or her mouth when sneezing is 0.29. If 10 randomly selected individuals are observed, compute the following probabilites. Your answers should be rounded to four decimal places. The probability that five individuals will cover their mouth when sneezing is The probability that six or less individuals will cover their mouth when sneezing is

A soccer team estimates that they wil score on 12% of the comer kicks. In next week's game, the team hopes to kick 13 coner kicks. What are the chances that they will score on 4 of those opportunities? The probability is (Type an integer or a decimal. Round to three decimal places as needed.)

Assume that when adults with smartphones are randomly selected, 39% use them in meetings or classes. If 15 adult smartphone users are randomly selected, find the probability that exactly 9 of them use their smartphones in meetings or classes. The probability is (Round to four decimal places as needed.)

Assume that when adults with smartphones are randomly selected, 54% use them in meetings or classes. If 10 adult smartphone users are randomly selected, find the probability that at least 8 of them use their smartphones in meetings or classes. The probability is. (Round to four decimal places as needed.)

A survey showed that 79​% of adults need correction​ (eyeglasses, contacts,​ surgery, etc.) for their eyesight. If 15 adults are randomly​ selected, find the probability that at least 14 of them need correction for their eyesight. Is 14 a significantly high number of adults requiring eyesight​ correction? The probability that at least 14 of the 15 adults require eyesight correction is nothing. ​(Round to three decimal places as​ needed.)
