Question

HELP://// The board of directors of a company knows that the probability that the carbon emission from the company’s manufacturing unit is exceeding the permissible level is 35%. A consultant is hired to use a carbon footprint calculator to test for the emission level. The accuracy of this test is said to be 85%.

What is the probability that the carbon emission from the manufacturing unit is within the permissible level, and the test predicts the same outcome?

0.2975
0.0525
0.0975
0.5525
0.6325

Answer 1

it says AND right, not GIVEN

Answer 2

uh what???

Answer 3

ok nvm
what is the probability that it is within the permissible level?

Answer 4

i literally don't understand any of this

Answer 5

would it be 35%??

Answer 6

ok lets take is slow (we can do it easy)
the probability that is NOT in the permissible level is .35 because that is what you are told

Answer 7

but you need the probability that it IS in the permissable level
so
\[100\%-35\%=?\]

Answer 8

65%

Answer 9

right,
as a decimal?

Answer 10

you have to convert the percent to a decimal

\[65\%=.65\]

Answer 11

and \(85\%\) is \(.85\)
all you need to do is multiply the decimals together to get your answer

Answer 12

.5525

Answer 13

as always, it is C

Answer 14

thank you so much you made it actually make sense. I might need your help on some more

Answer 15

ahahhaha thats funny I always go with c when I'm guessing

Answer 16

ok
what i didn't say was that you multiply because it said AND

Answer 17

What is the probability that the carbon emission from the manufacturing unit is within the permissible level, AND the test predicts the same outcome?

Answer 18

yeah C is always the best guess

Answer 19

so if it says and then you just multiply the two together
