A survey showed that 72 % of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 18 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?

    Step-by-step explanation:

    Given that a survey showed that 72 % of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight

    X - number of people who need correction for their eyesight

    X is binomial since each event is independent and there are only two outcmes.

    X (18, 0.72)

    Required probability = the probability that no more than 1 of them need correction for their eyesight.

    =P (X=0) + P (X=1) = 0.00000296+0.000137

    =0.00014

    Yes 1 is a significantly low number as probability is almost zero.
