Question

500 cats were chosen. 52% of the cats liked to sleep inside the house. Fish was the favorite dish of 25% of those cats, while 62.5% of the cats sleeping outside had another favorite dish. How many cats like fish? What's the probability that it likes fish and sleeps inside? How many cats don't like fish? How many cats in the sample like to sleep outside and like fish?

Answer 1

150 cats like fish. You could use a calculator btw.

Answer 2

You would need to take 500 * .52 = 260 next take 260 * .25 to find how many cats like fish which equals 65, the probability that it likes fish and it sleeps inside can be found by taking .52 * .25 = .13 so there would be a 13% chance of picking a cat that sleeps indoors and likes fish, 435 cats dont like fish found by taking 500-65=435 and finally to find how many cats sleep outside take 500-260=240 then take 240 * .625 = 150 then 240-150 = 90 so 90 cats like to sleep outside and like fish thats it!=) Hope this helps!
