Question

According to a center for disease​ control, the probability that a randomly selected person has hearing problems is. The probability that a randomly selected person has vision problems is.

Answer 1

No, because hearing and vision problems are not mutually exclusive.​ So, some people have both hearing and vision problems. These people would be included twice in the probability.

What is the possible probability of picking a blind or deaf person at random?

No, because there is no distinction between hearing and vision problems. As a result, some people experience difficulties with their hearing and vision.

When two events take place at different times, are they independent of one another?

Students frequently use the terms independent and disjunct interchangeably. The following is the primary distinction: Two occurrences are said to be discontinuous if they cannot happen at the same time. We argue that two occurrences are independent if neither one's likelihood of happening is impacted by the other's.
