Question

Assume that when an adult is randomly selected, the probability that they do not require vision correction is 17%. If 12 adults are randomly selected, find the probability that exactly 3 of them require vision correction. Round in three decimal places.

Answer #1

**Solution** :

The probability that they do not require vision correction is 17%

P(do not require vision correction) =0.17

P(require vision correction) = 1 - 0.17 = 0.83

Probability that exactly three of them require vision correction is given by,

So, probability = 0.000 (Round to three decimal places)

Also calculated by Excel BINOMDIST(3,12,0.83,0)

ANSWER IS 100 % CORRECT. THANK YOU!!

Assume that when an adult is randomly selected, the probability
that they do not require vision correction is 27%. If 9 adults are
randomly selected, find the probability that exactly 2 of them do
not require a vision correction. If 9 adults are randomly
selected, the probability that exactly 2 of them do not require a
vision correction is 0. (Round to three decimal places as
needed.)

Assume that when an adult is randomly selected, the probability
that they do not require vision correction is 18%.If 12 adults are
randomly selected, find the probability that fewer than 4 of them
do not require a vision correction.
If 12 adults are randomly selected, the probability that fewer
than 4 of them do not require a vision correction is _________?
