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.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

answer: a.   one is a factor of every whole number since every number is divisible by itself.
