Asurvey showed that 84% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. if 22 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?

Answer with explanation:

The binomial distribution formula :-

, where P(x) is the probability of getting success in x trials , n is total number of trials and p is the probability of getting success in each trial.

Given : The probability that adults need correction for their eyesight = 0.84

If 22 adults are randomly selected, then the probability that no more than 1 of them need correction for their eyesight .

which is much lower than 0.5 .

Yes , 1 is significantly low number of adults requiring eyesight correction .

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
