Employees in an office wear eyeglasses. 23 have single-wision correction, and 25 wear bifocals. If two employees are selected at random from this group, the probability that both of them wear bifocals? What is the probability that both have single-vision correction? Round your answers to four decimal places. and 25 wear bifocals. If two employees are selected at random from this group, what is both employees wear bifocals )-ta2607 both employees have single-vision correction

26.60% probability that both of them wear bifocals.

22.43% probability that both have single-vision correction.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, the order of the employees is not important. For example, John and Elisa, or Elisa and John are the same outcomes.

This is why we use the combinations formula:

is the number of different combinations of x objects from a set of n elements, given by the following formula.

Total outcomes:

23+25 = 48 employees

Two selected. So

What is the probability that both of them wear bifocals?

25 wear bifocals.

Two selected. So

26.60% probability that both of them wear bifocals.

What is the probability that both have single-vision correction?

23 have single vision correction.

Two selected. So

22.43% probability that both have single-vision correction.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

john got lost so he didn't know what to do and it was crazy because he didn't except it
