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 significantlylow 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.)
