In the united states, 75 percent of adults wear glasses or contact lenses. a random sample of 10 adults in the united states will be selected.
what is closest to the probability that fewer than 8 of the selected adults wear glasses or contact lenses?

0.4745 is the probability that fewer than 8 of the selected adults wear glasses or contact lenses.

Step-by-step explanation:

We are given the following information:

We treat adult adults wear glasses or contact lenses as a success.

P(Adults wear glasses or contact lenses) = 75% = 0.75

Then the number of adults follows a binomial distribution, where

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 10

We have to evaluate:

P(fewer than 8 of the selected adults wear glasses or contact lenses)

0.4745 is the probability that fewer than 8 of the selected adults wear glasses or contact lenses.

b) well because you get well

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
