Question

Part A

There were 600 water samples taken for an experiment using pH and iron levels. The results are shown in the table.
What are the probabilities for the listed events? Write your answers as decimals rounded to the thousandths place.

Answer 1

The answer to your problem is, 0.275 0.273 0.400 and 0.300

Explanation:

My calculation ( May not be correct )

P ( low iron or LI )
`(165)/(600)` = 0.275

P ( low pH | LI ) =
`(45)/(165)` = 0.273

P ( low pH ) =
`(150)/(600)` = 0.400

P ( LI | Low pH ) =
`(45)/(150)` = 0.300

Thus by making these calculations the answer to your problem is, 0.275 0.273 0.400 and 0.300
