Question

The corporate board of directors is hiring a consultant to do a deep analysis of one randomly selected XYZ manufacturing site. Given that 7 of the 14 XYZ sites have had 95% or higher widget production success rate in the last month, what is the probability that a successful site will be selected

Answer 1

Hence, the probability of a successful site is :

`P(\text{succes sites})=(8)/(9)=89\%`

Explanation:

Given :

`7` of the
`14,XYZ` sites have had
`95\%` or higher widget production success rate in the last month

To find :

The probability that a successful site will be selected.

We can select either of
`8` sites out of
`9`.

These
`8` sites can be selected in
`8` ways.

Total sites
`=9`

Therefore, the probability of a successful site is :

`P(\text{succes sites})=(8)/(9)=89\%`
