Answer:
0.2508
Step-by-step explanation:
The question asks for a conditional probability.
P(a household owns a dog if it owns a pet) = 0.67
Then P(a household does not own a dog if it owns a pet) = 1 - 0.67 = 0.33
P(a household owns a cat if it owns a pet) = 0.24
Then P(a household does not own a cat if it owns a pet) = 1 - 0.24 = 0.76
P(if a household owns a pet but the pet is not a cat or dog) = P(if a household owns a pet, it does not own a cat) × P(if a household owns a pet, it does not own a dog) = 0.33 × 0.76 = 0.2508
First to see how Much Norm used, we need to subtract 373 from 500 (500-373) and you get 127. To express this as a fraction you put 127 over 500. then the decimal would be 127 divided into 500. Which is .254 . The answer in fraction form is 127/500 and in decimal is .254

there is no table appearing so unfortunately no one can answer this for you. sorry!!
Hi!
So, to "half" a number, you multiply it by 1/2 or 0.5
"A number" is a number which we don't know the value of, so we could use a variable. Any letter you want is fine, but let's use x
"Decrease by 12" This simply means to subtract 12, so - 12
So, now we have:
1/2x - 12
