Another probability?

Question

A toy company tested 1000 dolls and found out that 25 of them will not "cry" when a button is pushed. What is the probability that a doll from this company will actually "cry"when a child pushes the button?

plzz explain how you worked the eqaution and what you got as the anwer so i undestand better.

thankyou : )

Answer 1

(1000-25)/1000 is the probability.  .975

In the sample population of 1000, 25 did not cry.

So the number that did cry is 1000-25.

Then divide by the size of the sample to get the probability ratio.

If you want that probability represented as a percentage, then multiply by 100, to get 97.5%

Answer 2

Equation = (25/1000)*100

I think the explanation is number of positive results (or negative results, either way, the thing you need to find out goes in this spot) divided by total possible results, this gives the result as a decimal, you then times by 100 to convert it to percent. Hope that makes sense

Answer 3

the empirical probability is 25/1000 = 0.025

this is an estimate for the true population proportion.
